Answer 2

Problem Analysis

In this problem, we are given that a bus and a truck started moving in opposite directions from the same city. After 4 hours, the distance between them was 528 km. We are also given the speed of the bus, and we need to find the speed of the truck.

Solution

Let's assume the speed of the truck is x km/h.

The distance covered by the bus in 4 hours is 58 km/h * 4 h = 232 km.

The distance covered by the truck in 4 hours is x km/h * 4 h = 4x km.

Since the total distance between them is 528 km, we can write the equation:

232 km + 4x km = 528 km

To find the speed of the truck, we need to solve this equation for x.

Calculation

Let's solve the equation:

232 km + 4x km = 528 km

Subtract 232 km from both sides:

4x km = 528 km - 232 km

4x km = 296 km

Divide both sides by 4:

x km = 296 km / 4

x km = 74 km/h

Answer

Therefore, the speed of the truck is 74 km/h.
