Question: Manex is a tour bus driver. He has to drive 55 miles to the destination and drive going back to the starting point on a different way that is 10 miles farther. If he can drive 1 mile for 2 minutes and stayed 2 hours at the destination, how long will it take the bus driver to do the entire tour in hours?
Answer:
The bus traveled 55 + 10 = 65 miles going back to the starting point. So, the bus traveled a total of 55 + 65 = 120 miles. It took 120 x 2 = 240 minutes to travel. Since there are 60 minutes in 1 hour, then the bus traveled for 240 / 60 = 4 hours. Therefore, the entire tour took 4 + 2 = 6 hours. The answer is 6.
