(a)
Distance that Andy covered when he jogged 2 minutes earlier
= 2 x 200
= 400 m
Distance that Asher covered more than Andy per min
= 250 - 200
= 50 m
Time that Asher needed to take to cover the additional 400 m
= 400 ÷ 50
= 8 min
(b)
Time that Andy would had jogged when Asher caught up with him
= 8 + 2
= 10 min
Distance that Andy would have jogged when Asher caught up with him
= 10 x 200
= 2000 m
Answer(s): (a) 8 min; (b) 2000 m
