(a)
Distance that Fabian covered when he jogged 2 minutes earlier
= 2 x 300
= 600 m
Distance that Flynn covered more than Fabian per min
= 400 - 300
= 100 m
Time that Flynn needed to take to cover the additional 600 m
= 600 ÷ 100
= 6 min
(b)
Time that Fabian would had jogged when Flynn caught up with him
= 6 + 2
= 8 min
Distance that Fabian would have jogged when Flynn caught up with him
= 8 x 300
= 2400 m
Answer(s): (a) 6 min; (b) 2400 m
