• im-Bob bicycled 1.4 miles in 12 min from his home to the Fargodome to watch the Bison football game, where he watched the game for 2.0 hr. During the game, his bicycle was stolen, so he had to walk home, which took him 28 min. What was his average speed for the entire trip?

• Answer:

  Average speed has nothing to do with the 2 hr game Average speed = total distance/total time total distance here is 1.4+1.4 miles (home to Fargodome + Fargodome to home)= 2.8 total time= 12+28 = 40 min Hence average speed = 2.8/40 = 0.07 miles/min or 4.2 miles/hr
