PITU CW 4.2 Speed, Average Speed, Velocity Packet Name: _____________________ Per: ____ Speed, Distance, & Time 1) Sidek travels 450 km in 5 hours. What was his speed in km/h? Speed = Distance = Time = Speed = _________ ÷ ____________ = ________ km/h 2) A car travels at an average speed of 60 km/h. How long will it take for the car to travel 120 km? Give your answer in minutes. Speed = Distance = Time = Time = _________ ÷ ____________ = ________ hours = _________ min 3) An airplane flies at a speed of 850 km/h for 8 hours. How far did the plane travel? Speed = Distance = Distance = _________ 𝑥 ____________ = ________ km Time = Compare Speeds Calculate the speed of each object. You must show your math and final speed for each object/person even if logically you can figure it out. Place a circle around the fastest. A bus takes 2 hours to travel a distance of 100 km A car takes 4 hours to travel in a distance of 100 km Muthu takes 15 minutes to cycle to school every morning. Samad takes 12 minutes to cycle to the same school and it’s the same distance as Muthu. In a 100 m race, Alia takes only 11 seconds to reach the finish line. In a 100 m race, Swee Ting takes only 11.5 seconds to reach the finish line. The distance from Ipoh to Kuala Lumpur is 210 km and train A travels for 2 hours to reachKuala Lumpur. Train B takes only 2 hours to travel a distance of 350 km from Penang to Kuala Lumpur. Faridah walks to the market which is 50 m away from her house and she takes only 5 minutes to reach there. Rohani walks to the market which is 35 m away from her house and she also takes 5 minutes to reach the market. 9) Ron walks 22.5 km in a curve to the east in 5 hours. Find his speed and velocity. Formula for speed: Formula for velocity: Solve for speed (show steps): Speed answer with units: Solve for velocity (show steps): Velocity answer with units and direction: 10) A train covers 168 km southeast in 4 hours. Find its speed and velocity. Formula for speed: Formula for velocity: Solve for speed (show steps): Speed answer with units: Solve for velocity (show steps): Velocity answer with units and direction: 11) Rachel traveled 240 km south in 4 hours by train and then traveled 120 km east in 3 hours by car. Speed of train: Speed of car: Average speed of whole trip: Velocity of whole trip: 12) A car moves from A to B at a speed of 50 km/hr east and comes back heading west from B to A at a speed of 30 km/hr. Label the diagram with the information you were given. Calculate average speed: Total Distance: Total Time: Calculate velocity: Answer with units: 13) A plane covers a distance of 600 m in 20 minutes whereas a train covers a distance of 75 km in 50 minutes. Calculate the speed of each. Plane Train Solve (show formula & steps): Solve (show formula & steps): Answer with units: Answer with units: 14) Anjali drives a car distance of 60 km east in 3 hours towards Las Vegas. After stopping in St. Bruno for lunch. The car travels 70 km northeast for another 3 hours and stops for gas in Unionville before continuing to Las Vegas. The last leg took 2.5 hour to travel 55 km northeast. If a bird flew straight from the house to Las Vegas the distance would be 100 km. Label the diagram with the information you were given. What is the speed for the first leg of the trip (home to St Bruno)? What is the speed for the second leg of the trip (St. Bruno to Unionville)? What is the speed for the last leg of the trip (Unionville to Las Vegas)? Average speed of whole trip: Velocity of whole trip: Distance Time Graphs: 15) The distance-time graph shows class 8A’s journey to the zoo which is located to the south of the school. They stopped for a picnic on the way to the zoo. a) What time did the bus leave school? b) What time did they stop for a picnic? c) How far had they traveled when they stopped for a picnic? d) How long did they stop for? e) What time did they arrive at the zoo? f) How far is the zoo from school? g) What speed did the bus travel from the school to the picnic spot? h) What was the speed from 10:00am to 10:30am? Prove your answer with math and explain what it means in the context of this situation. i) Calculate the average speed for the trip. j) Calculate the velocity for the trip. 16) Emma traveled to her Grandma’s house and back. Grandma lives northwest of Emma. The distance-time graph shows information about her journey. k) What time did Emma leave the house? l) m) How far was Emma from home at 8am? n) How long did Emma stay at her Grandma’s house? o) What time did Emma leave Grandma’s house? p) How far is Emma from home at 11:45am? q) How far did Emma travel in total? r) What speed was Emma traveling on her way to Grandma’s? s) What speed was Emma traveling on the way home from Grandma’s? t) Calculate the average speed for the trip. u) Calculate the velocity for the trip.
