Reasoning and answer: Making the round trip to school means driving from the house to school and then back, for a total of 2.5 + 2.5 = 5 miles. He makes this trip twice in one day for a total of 2 * 5 = 10 miles. He does this 4 times in a week for a total of 4 * 10 = 40 miles. The round trip (once a week) to the market is 2 + 2 = 4 miles. His total mileage for a typical week = 40 + 4 = 44 miles.
The answer: 44
