(not multiple choice) If a car travels at a constant rate of speed, the distance that it travels varies directly as time. If a car travels 75 miles in 2.5 hours, it will travel 110 feet in 2.5 seconds.

a. Find the constant of variation in miles per hour
b. Draw a graph that compares the distance that the car travels in miles to the number of hours traveled. Let the horizontal axis represent minutes and the vertical axis represents characters.
c. Find the constant of variation in feet per second.
d. Draw a graph that compares the distance the car travels in feet to the number of seconds traveled.
