Ethan and Pierre started jogging from the same point. Pierre started jogging 4 minutes earlier than Ethan. Ethan's jogging speed was 500 m/min and Pierre'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 Ethan to catch up with Pierre? 
2. What distance would Pierre have jogged when Ethan caught up with him?  Express your answer in meters.

	Ethan	Pierre
Speed	500 m/min	300 m/min
Start time		4 min earlier
Extra distance covered at first		1200 m

(a)
Distance that Pierre covered when he jogged 4 minutes earlier
= 4 x 300
= 1200 m

Distance that Ethan covered more than Pierre per min
= 500 - 300
= 200 m

Time that Ethan needed to take to cover the additional 1200 m
= 1200 ÷ 200
= 6 min

(b)
Time that Pierre would had jogged when Ethan caught up with him
= 6 + 4
= 10 min

Distance that Pierre would have jogged when Ethan caught up with him
= 10 x 300
= 3000 m

Answer(s): (a) 6 min; (b) 3000 m
