(a)
Distance that Vincent covered when he jogged 6 minutes earlier
= 6 x 250
= 1500 m
Distance that Cody covered more than Vincent per min
= 350 - 250
= 100 m
Time that Cody needed to take to cover the additional 1500 m
= 1500 ÷ 100
= 15 min
(b)
Time that Vincent would had jogged when Cody caught up with him
= 15 + 6
= 21 min
Distance that Vincent would have jogged when Cody caught up with him
= 21 x 250
= 5250 m
Answer(s): (a) 15 min; (b) 5250 m
