John and Oscar started jogging from the same point. Oscar started jogging 3 minutes earlier than John. John's jogging speed was 400 m/min and Oscar's jogging speed was 200 m/min. They went in the same direction and did not change their speeds throughout.

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

	John	Oscar
Speed	400 m/min	200 m/min
Start time		3 min earlier
Extra distance covered at first		600 m

(a)
Distance that Oscar covered when he jogged 3 minutes earlier
= 3 x 200
= 600 m

Distance that John covered more than Oscar per min
= 400 - 200
= 200 m

Time that John needed to take to cover the additional 600 m
= 600 ÷ 200
= 3 min

(b)
Time that Oscar would had jogged when John caught up with him
= 3 + 3
= 6 min

Distance that Oscar would have jogged when John caught up with him
= 6 x 200
= 1200 m

Answer(s): (a) 3 min; (b) 1200 m
