a) Draw a number line and label an origin as point “0”. Mark the initial positions of each object
above the line. Use abbreviations like C1 for the initial position of the car, etc. [3]
b) Mark the final positions of each object below the line. Use abbreviations like C2 for the final
position of the car, etc. [2]
c) Calculate the displacement of each object, using the formula for ∆𝑑. [4]
car 
bike 
pedestrian 
skateboarder 
2. Two taxis are travelling along Saskatchewan Ave. in opposite directions. Taxi X changes its position
from +3 to +11 during the same time as taxi Y changes from +3 to -7. Draw a diagram to show the initial
and final positions of each taxi. Then calculate the displacement for each taxi. [4]
3. Define: instant of time –

4. Convert the following: [9]
a) 72 km/h to m/s
b) 10 m/s to km/h
c) 100 km/h to m/s
d) 2.5 m/s to km/h
e) 1 hr 17 min 12 s to seconds
f) 2.34 hr to hr & min & sec

g) 0.25 km/min to km/hr
5. What is the velocity of a person walking 950 m in 21 min? Answer in m/s. [3]
6. If a car travels 28 km in 17 min, how many km/h is it going? [3]
7. How long will it take for a biker, travelling at 12 km/h, to drive 3 km. Answer in minutes. [3]
8. How far does a car travel in 3 hr and 16 min if it’s travelling at 96 km/h? [3]
9. If the distance from Portage to Winnipeg is 72 km, how long would it take a person travelling at an
average speed of 89 km/h to drive from Portage to Winnipeg? Answer in minutes and seconds. [3]
10. If a duck can fly at 68 km/h for a duration of 2 hours and 12 minutes before slowing down, how far
will it travel? [3]
