Question

Monica has a goal to complete a triathlon. The race consists of a 2.4-mile swim, a 112-bike ride, and a 26.2-mile run. In training, Monica can swim at an average pace of 1.8 mph. She rides her bike at an average of 20.8 mph and runs at 5.1 mph. Estimate how long it will take her to complete the triathlon.

Answer 1

ok

For swimming

t = distance / speed

t = 2.4/1.8 = 1.33 h

For ridding

t = 112 / 20.8

t = 5.4 h

For running

t = 26.8 / 5.1

t = 5.3 h

Total time

t = 5.4 + 1.3 + 5.3

t = 12 h

Result = 12 hours
