(a)
Distance that Neave covered when he jogged 5 minutes earlier
= 5 x 150
= 750 m
Distance that Cole covered more than Neave per min
= 400 - 150
= 250 m
Time that Cole needed to take to cover the additional 750 m
= 750 ÷ 250
= 3 min
(b)
Time that Neave would had jogged when Cole caught up with him
= 3 + 5
= 8 min
Distance that Neave would have jogged when Cole caught up with him
= 8 x 150
= 1200 m
Answer(s): (a) 3 min; (b) 1200 m
