Question

Akash and Bryston took part in their school’s mini-marathon which started at 8.00a.m. Akash’s average speed was 35m/min faster than Bryston. When Akash completed the mini-marathon in 42 minutes, Bryston had only run 7/8 of the distance.

a) What time did Bryston complete the mini-marathon?

b) Find Akash’s average speed for the mini-marathon in m/min

Answer

a) (8/7) * 42min = 48min

b) 1/8 distance: 42min * 35m / min = 1,470m

Full marathon distance: 1,470m * 8 = 11,760m

Akash’s speed = 11,760m / 42min = 280m/min
