First multiply 76 by 60 to find how many feet in a minute =4,560. Then multiply 4,560 by 60 to find how many feet per hour =273,600. Then multiply 273,600 by 3.1 to find how many feet in 3.1 hours =848,160. Then divide 848,160 by 5,280 (number of feet per mile) to find how many miles in 3.1 hours =160.636. Round 160.636 to nearest tenth =160.6 :) hope this makes sense
