Eric and Ken started jogging from the same point. Ken started jogging 7 minutes earlier than Eric. Eric's jogging speed was 400 m/min and Ken's jogging speed was 350 m/min. They went in the same direction and did not change their speeds throughout.

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

	Eric	Ken
Speed	400 m/min	350 m/min
Start time		7 min earlier
Extra distance covered at first		2450 m

(a)
Distance that Ken covered when he jogged 7 minutes earlier
= 7 x 350
= 2450 m

Distance that Eric covered more than Ken per min
= 400 - 350
= 50 m

Time that Eric needed to take to cover the additional 2450 m
= 2450 ÷ 50
= 49 min

(b)
Time that Ken would had jogged when Eric caught up with him
= 49 + 7
= 56 min

Distance that Ken would have jogged when Eric caught up with him
= 56 x 350
= 19600 m

Answer(s): (a) 49 min; (b) 19600 m
