Question

Person runs 22 kms in 1 hour and 7 minutes how long does it take to run 28 kms?

Answer 1

let x = distance and y = time

so 22 km / 67 mins = 28 km  / y

22kms (y) = 1876 km-mins

y = 1876 km-mins / 22 kms

y = 85.27 mins

Answer 2

22/67 = 28/x

28*67 = 22x

22x = 1876

x ≈ 85.273 min.

Assuming the runner keeps the same pace in the 28km as the 22km, it should take him/her abour 1 hr 25 min 16 sec.  With 6 more kilometers though, they would probably pace themselves a little more to get about an hour an a half.
