Eric and Sam started jogging from the same point. Sam started jogging 3 minutes earlier than Eric. Eric's jogging speed was 500 m/min and Sam'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 Sam? 
2. What distance would Sam have jogged when Eric caught up with him?  Express your answer in meters.

	Eric	Sam
Speed	500 m/min	350 m/min
Start time		3 min earlier
Extra distance covered at first		1050 m

(a)
Distance that Sam covered when he jogged 3 minutes earlier
= 3 x 350
= 1050 m

Distance that Eric covered more than Sam per min
= 500 - 350
= 150 m

Time that Eric needed to take to cover the additional 1050 m
= 1050 ÷ 150
= 7 min

(b)
Time that Sam would had jogged when Eric caught up with him
= 7 + 3
= 10 min

Distance that Sam would have jogged when Eric caught up with him
= 10 x 350
= 3500 m

Answer(s): (a) 7 min; (b) 3500 m
