(a)
Distance that Tommy covered when he jogged 8 minutes earlier
= 8 x 150
= 1200 m
Distance that Nick covered more than Tommy per min
= 350 - 150
= 200 m
Time that Nick needed to take to cover the additional 1200 m
= 1200 ÷ 200
= 6 min
(b)
Time that Tommy would had jogged when Nick caught up with him
= 6 + 8
= 14 min
Distance that Tommy would have jogged when Nick caught up with him
= 14 x 150
= 2100 m
Answer(s): (a) 6 min; (b) 2100 m
