(a)
Distance that Flynn covered when he jogged 6 minutes earlier
= 6 x 250
= 1500 m
Distance that Eric covered more than Flynn per min
= 500 - 250
= 250 m
Time that Eric needed to take to cover the additional 1500 m
= 1500 ÷ 250
= 6 min
(b)
Time that Flynn would had jogged when Eric caught up with him
= 6 + 6
= 12 min
Distance that Flynn would have jogged when Eric caught up with him
= 12 x 250
= 3000 m
Answer(s): (a) 6 min; (b) 3000 m
