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

Answer:

14 minutes

Step-by-step 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
