Problem Analysis

We are given that a bus traveled 1/7 of the total distance in the first hour and 5/6 of the distance it traveled in the first hour in the second hour. We need to find out how many kilometers are left for the bus to travel if the total distance is 420 km.

Solution

Let's solve the problem step by step:

1. Calculate the distance traveled in the first hour: - The bus traveled 1/7 of the total distance in the first hour. - Therefore, the distance traveled in the first hour is (1/7) * 420 km = 60 km.

2. Calculate the distance traveled in the second hour: - The bus traveled 5/6 of the distance it traveled in the first hour in the second hour. - Therefore, the distance traveled in the second hour is (5/6) * 60 km = 50 km.

3. Calculate the total distance traveled in the first two hours: - The total distance traveled in the first two hours is the sum of the distances traveled in the first hour and the second hour. - Therefore, the total distance traveled in the first two hours is 60 km + 50 km = 110 km.

4. Calculate the distance remaining to be traveled: - The total distance is 420 km, and the bus has already traveled 110 km in the first two hours. - Therefore, the distance remaining to be traveled is 420 km - 110 km = 310 km.

Answer

The bus has 310 kilometers left to travel.
