Peter started to cycle 5 minutes after James started to cycle.

Answer 1

Answer:22

Explanation:

what the guy before said

Answer 2

22.48 km/h

Explanation:

it took James 45 minutes to cycle 15 km, sInce he was traveling at 20 km/h, which was worked out by dividing 50 by 2.5.

since Peter left 5 minutes later, it took 5 minutes less, so 40 minutes. 40 minutes as a fraction is 0.667.

15 divided by 0.667 is 22.48 km/h
