Question

A car travels at a speed of x miles per hour for 3 hours and at half that speed for 2 hours. Which expression gives the total distance the car traveled in 5 hours?

Answer 1

The total distance the car traveled in 5 hours is 4x miles.

Step-by-step explanation:

To find the total distance the car traveled in 5 hours, we can add the distance traveled at the speed of x miles per hour for 3 hours and the distance traveled at half that speed for 2 hours.

The distance traveled at the speed of x miles per hour for 3 hours is 3x miles.

The distance traveled at half that speed for 2 hours is (0.5x) * 2 = x miles.

Therefore, the total distance traveled in 5 hours is 3x + x = 4x miles.

Answer 2

x+x/2=5

one and a half x = 5 hours
