(a)
Distance that Tommy covered when he jogged 2 minutes earlier
= 2 x 150
= 300 m
Distance that Vaidev covered more than Tommy per min
= 250 - 150
= 100 m
Time that Vaidev needed to take to cover the additional 300 m
= 300 ÷ 100
= 3 min
(b)
Time that Tommy would had jogged when Vaidev caught up with him
= 3 + 2
= 5 min
Distance that Tommy would have jogged when Vaidev caught up with him
= 5 x 150
= 750 m
Answer(s): (a) 3 min; (b) 750 m
