Ivan and Ethan started jogging from the same point. Ethan started jogging 6 minutes earlier than Ivan. Ivan's jogging speed was 400 m/min and Ethan's jogging speed was 250 m/min. They went in the same direction and did not change their speeds throughout.

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

	Ivan	Ethan
Speed	400 m/min	250 m/min
Start time		6 min earlier
Extra distance covered at first		1500 m

(a)
Distance that Ethan covered when he jogged 6 minutes earlier
= 6 x 250
= 1500 m

Distance that Ivan covered more than Ethan per min
= 400 - 250
= 150 m

Time that Ivan needed to take to cover the additional 1500 m
= 1500 ÷ 150
= 10 min

(b)
Time that Ethan would had jogged when Ivan caught up with him
= 10 + 6
= 16 min

Distance that Ethan would have jogged when Ivan caught up with him
= 16 x 250
= 4000 m

Answer(s): (a) 10 min; (b) 4000 m
