Question

Two equations are written to express how far a car can go when driving on different roads. On Road 1, the car can go 60 miles in 2 hours. On Road 2, the car can go 90 miles in 4 hours. Write an equation where y
is the distance in miles and x is the time in hours to represent the motion of the faster car.(1 point)

Answer 1

For Road 1, the car can go 60 miles in 2 hours. The equation representing this motion is:
y = 30x

For Road 2, the car can go 90 miles in 4 hours. The equation representing this motion is:
y = 22.5x

Since we are looking for the equation representing the motion of the faster car, we can use the equation for Road 2:
y = 22.5x
