(a)
Distance that Bryan covered when he jogged 10 minutes earlier
= 10 x 250
= 2500 m
Distance that Flynn covered more than Bryan per min
= 500 - 250
= 250 m
Time that Flynn needed to take to cover the additional 2500 m
= 2500 ÷ 250
= 10 min
(b)
Time that Bryan would had jogged when Flynn caught up with him
= 10 + 10
= 20 min
Distance that Bryan would have jogged when Flynn caught up with him
= 20 x 250
= 5000 m
Answer(s): (a) 10 min; (b) 5000 m
