(a)
Distance that Zane covered when he jogged 6 minutes earlier
= 6 x 200
= 1200 m
Distance that Ben covered more than Zane per min
= 500 - 200
= 300 m
Time that Ben needed to take to cover the additional 1200 m
= 1200 ÷ 300
= 4 min
(b)
Time that Zane would had jogged when Ben caught up with him
= 4 + 6
= 10 min
Distance that Zane would have jogged when Ben caught up with him
= 10 x 200
= 2000 m
Answer(s): (a) 4 min; (b) 2000 m
