(a)
Distance that Neave covered when he jogged 6 minutes earlier
= 6 x 300
= 1800 m
Distance that Daniel covered more than Neave per min
= 500 - 300
= 200 m
Time that Daniel needed to take to cover the additional 1800 m
= 1800 ÷ 200
= 9 min
(b)
Time that Neave would had jogged when Daniel caught up with him
= 9 + 6
= 15 min
Distance that Neave would have jogged when Daniel caught up with him
= 15 x 300
= 4500 m
Answer(s): (a) 9 min; (b) 4500 m
