(a)
Distance that Fabian covered when he jogged 4 minutes earlier
= 4 x 200
= 800 m
Distance that Cody covered more than Fabian per min
= 250 - 200
= 50 m
Time that Cody needed to take to cover the additional 800 m
= 800 ÷ 50
= 16 min
(b)
Time that Fabian would had jogged when Cody caught up with him
= 16 + 4
= 20 min
Distance that Fabian would have jogged when Cody caught up with him
= 20 x 200
= 4000 m
Answer(s): (a) 16 min; (b) 4000 m
