Question

10) Pete is fast, Repeat is 3 times faster. If

Pete and Repeat can complete the job in
56 minutes, how fast is Pete? (I want
Pete's time only)

Answer 1

14 minutes

Explanation:

if Pete is x times fast then Repeat is 3x faster

so if both combine to complete a job in 56 minutes then we have

`x + 3x = 56 \\ 4x = 56 \\ x = 14`

remember Pete is x hence Pete was 14 minutes fast
