(a)
Distance that Carl covered when he jogged 10 minutes earlier
= 10 x 300
= 3000 m
Distance that Owen covered more than Carl per min
= 350 - 300
= 50 m
Time that Owen needed to take to cover the additional 3000 m
= 3000 ÷ 50
= 60 min
(b)
Time that Carl would had jogged when Owen caught up with him
= 60 + 10
= 70 min
Distance that Carl would have jogged when Owen caught up with him
= 70 x 300
= 21000 m
Answer(s): (a) 60 min; (b) 21000 m
