The football coach makes his players run up and down the bleachers 40 times. Each time they run up and down 32 stairs one way. If each stair burns 2 calories, how many calories does each player burn during this exercise?
How many stairs are in each bleacher? ** First find the number of stairs the players climb up and down each time: 32 stairs * 2 = <<32*2=64>>64 stairs
How many stairs do the players climb? ** Then multiply the number of stairs per run by the number of runs to find the total number of stairs the players climb: 64 stairs/run * 40 runs = <<64*40=2560>>2560 stairs
How many calories do the players burn? ** Then multiply the number of stairs by the number of calories each stair burns: 2560 stairs * 2 calories/stair = <<2560*2=5120>>5120 calories
