Oscar and Sean started jogging from the same point. Sean started jogging 7 minutes earlier than Oscar. Oscar's jogging speed was 200 m/min and Sean's jogging speed was 100 m/min. They went in the same direction and did not change their speeds throughout.

1. How long did it take for Oscar to catch up with Sean? 
2. What distance would Sean have jogged when Oscar caught up with him?  Express your answer in meters.

	Oscar	Sean
Speed	200 m/min	100 m/min
Start time		7 min earlier
Extra distance covered at first		700 m

(a)
Distance that Sean covered when he jogged 7 minutes earlier
= 7 x 100
= 700 m

Distance that Oscar covered more than Sean per min
= 200 - 100
= 100 m

Time that Oscar needed to take to cover the additional 700 m
= 700 ÷ 100
= 7 min

(b)
Time that Sean would had jogged when Oscar caught up with him
= 7 + 7
= 14 min

Distance that Sean would have jogged when Oscar caught up with him
= 14 x 100
= 1400 m

Answer(s): (a) 7 min; (b) 1400 m
