Football A tight end can run the 100-yard dash in 12 seconds. A defensive back can do it in 10 seconds. The tight end catches a pass at his own 20-yard line with the defensive back at the 15-yard line. (See the figure-top, right.) If no other players are nearby, at what yard line will the defensive back catch up to the tight end?
