The bus driver drives an average of 2 hours each day, 5 days a week. From Monday to Wednesday he drove at an average speed of 12 kilometers per hour, and from Thursday to Friday at an average speed of 9 kilometers per hour. How many kilometers did the driver travel during these 5 days?
From Monday to Wednesday, there are 3 * 2 = <<3*2=6>>6 hours of work.
During this time the driver drove 6 * 12 = <<6*12=72>>72 kilometers.
On Thursday and Friday, there are 2 * 2 = <<2*2=4>>4 hours of work in total.
During this time the driver drove 4 * 9 = <<4*9=36>>36 kilometers.
So in total, the driver traveled 72 + 36 = <<72+36=108>>108 kilometers during these five days.
