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)
For Road 1, the car can go 60 miles in 2 hours. The equation for this car on Road 1 is y = 60/2 = 30x.
For Road 2, the car can go 90 miles in 4 hours. The equation for this car on Road 2 is y = 90/4 = 22.5x.
Since we want to represent the motion of the faster car, we will use the equation for Road 2: y = 22.5x.
