Problem Analysis

To solve this problem, we need to determine the time it takes for the first bus to overtake the second bus. We are given the speeds of both buses and the distance by which the first bus needs to overtake the second bus.

Solution

Let's assume that the time it takes for the first bus to overtake the second bus is t hours. During this time, the first bus will travel a distance of 80t km, and the second bus will travel a distance of 70t km.

Since the first bus needs to overtake the second bus by 40 km, we can set up the following equation:

80t - 70t = 40

Simplifying the equation, we get:

10t = 40

Dividing both sides of the equation by 10, we find:

t = 4

Therefore, it will take the first bus 4 hours to overtake the second bus.

Summary

In summary, the first bus will overtake the second bus after 4 hours of travel.
