Compare Distance -Time Graph

Question 1
The red car travels at a rate of 60 miles per hour. Which equation is the BEST for describing the distance y of the blue car after x hours?
Responses
A y = 70xy = 70x
B y = 50xy = 50x
C y = 60xy = 60x
D y = 65x

Answer 1

The equation that best describes the distance y of the blue car after x hours is C: y = 60x. Since the red car is traveling at a rate of 60 miles per hour, the blue car must also be traveling at the same rate, so the equation should have a coefficient of 60.
