(a)
Distance that Brandon covered when he jogged 10 minutes earlier
= 10 x 350
= 3500 m
Distance that Tim covered more than Brandon per min
= 450 - 350
= 100 m
Time that Tim needed to take to cover the additional 3500 m
= 3500 ÷ 100
= 35 min
(b)
Time that Brandon would had jogged when Tim caught up with him
= 35 + 10
= 45 min
Distance that Brandon would have jogged when Tim caught up with him
= 45 x 350
= 15750 m
Answer(s): (a) 35 min; (b) 15750 m
