(a)
Distance that Jenson covered when he jogged 6 minutes earlier
= 6 x 250
= 1500 m
Distance that Reggie covered more than Jenson per min
= 400 - 250
= 150 m
Time that Reggie needed to take to cover the additional 1500 m
= 1500 ÷ 150
= 10 min
(b)
Time that Jenson would had jogged when Reggie caught up with him
= 10 + 6
= 16 min
Distance that Jenson would have jogged when Reggie caught up with him
= 16 x 250
= 4000 m
Answer(s): (a) 10 min; (b) 4000 m
