Question: Every day, while going to school, Shane drives a total of 10 miles. Calculate the total distance he drives in an 80 day semester from home to school and back. Think carefully first, then make a decision:
To go to school and back, Shane drives 2 * 10 = 20 miles per day. In 80 days of a semester, he drives for 80 * 20 = 1600 miles. So the answer is 1600.
