Problem Analysis

We are given that a bus traveled for 4 hours at a speed of 70 kilometers per hour. On the return trip, it took 5 hours. We need to determine the speed of the bus on the return trip.

Solution

To find the speed of the bus on the return trip, we can use the formula:

Speed = Distance / Time

Let's assume the distance traveled by the bus is D.

On the forward trip: - Time = 4 hours - Speed = 70 kilometers per hour

Using the formula, we can write: 70 = D / 4 On the return trip: - Time = 5 hours - Speed = unknown (let's call it S)

Using the formula, we can write: S = D / 5

To find the value of S, we can substitute the value of D from equation into the equation for the return trip speed:

S = (70 * 5) / 4

Simplifying the equation, we get: S = 87.5 kilometers per hour

Therefore, the speed of the bus on the return trip was 87.5 kilometers per hour.

Answer

The bus traveled at a speed of 87.5 kilometers per hour on the return trip.
