Ken and John started jogging from the same point. John started jogging 10 minutes earlier than Ken. Ken's jogging speed was 500 m/min and John's jogging speed was 300 m/min. They went in the same direction and did not change their speeds throughout.

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

	Ken	John
Speed	500 m/min	300 m/min
Start time		10 min earlier
Extra distance covered at first		3000 m

(a)
Distance that John covered when he jogged 10 minutes earlier
= 10 x 300
= 3000 m

Distance that Ken covered more than John per min
= 500 - 300
= 200 m

Time that Ken needed to take to cover the additional 3000 m
= 3000 ÷ 200
= 15 min

(b)
Time that John would had jogged when Ken caught up with him
= 15 + 10
= 25 min

Distance that John would have jogged when Ken caught up with him
= 25 x 300
= 7500 m

Answer(s): (a) 15 min; (b) 7500 m
