A bus and a car leave from the same city traveling in opposite directions. The bus leaves 2 hours before the car does. The bus travels at a steady speed of 50 mph while the car travels at 70 mph. After how many hours will the bus and car be 800 miles apart?If h represents the number of hours the bus travels, then which of the following expressions represents the number of miles the car travels?

Accepted Solution

A:
number of hours = h the bus left 2 hours before the car so the car traveled h-2 hours

The car travels at 70 mph. so the equation for the car is: 70(h-2)
