(a)
Distance that Michael covered when he jogged 5 minutes earlier
= 5 x 250
= 1250 m
Distance that Ahmad covered more than Michael per min
= 300 - 250
= 50 m
Time that Ahmad needed to take to cover the additional 1250 m
= 1250 ÷ 50
= 25 min
(b)
Time that Michael would had jogged when Ahmad caught up with him
= 25 + 5
= 30 min
Distance that Michael would have jogged when Ahmad caught up with him
= 30 x 250
= 7500 m
Answer(s): (a) 25 min; (b) 7500 m
