The number of calories a person burns in doing an activity can be approximated using the formula C = kmt, where m is the person’s weight in pounds and t is the duration of the activity in minutes. Find the units for the coefficient k. 3. Convert 60 miles per hour to feet per minute. 4. When Justin goes to work, he drives at an average speed of 65 miles per hour. It takes about 1 hour and 30 minutes for Justin to arrive at work. His car travels about 25 miles per gallon of gas. If gas costs $3.65 per gallon, how much money does Justin spent to travel each mile to work? 5. A rectangle has an area of 12m2 and width of 400 cm. What is the length of the rectangle? 6.
