(a)
Distance that Will covered when he jogged 8 minutes earlier
= 8 x 250
= 2000 m
Distance that Harry covered more than Will per min
= 350 - 250
= 100 m
Time that Harry needed to take to cover the additional 2000 m
= 2000 ÷ 100
= 20 min
(b)
Time that Will would had jogged when Harry caught up with him
= 20 + 8
= 28 min
Distance that Will would have jogged when Harry caught up with him
= 28 x 250
= 7000 m
Answer(s): (a) 20 min; (b) 7000 m
