<human>:  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.

How many miles does Shane drive in an 80 day semester? ** In 80 days of a semester, he drives for 80*20 = <<80*20=1600>>1600 miles
