(a)
Distance that Flynn covered when he jogged 7 minutes earlier
= 7 x 250
= 1750 m
Distance that Ivan covered more than Flynn per min
= 500 - 250
= 250 m
Time that Ivan needed to take to cover the additional 1750 m
= 1750 ÷ 250
= 7 min
(b)
Time that Flynn would had jogged when Ivan caught up with him
= 7 + 7
= 14 min
Distance that Flynn would have jogged when Ivan caught up with him
= 14 x 250
= 3500 m
Answer(s): (a) 7 min; (b) 3500 m
