Ethan and Julian started jogging from the same point. Julian started jogging 7 minutes earlier than Ethan. Ethan's jogging speed was 450 m/min and Julian'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 Julian? 
2. What distance would Julian have jogged when Ethan caught up with him?  Express your answer in meters.

	Ethan	Julian
Speed	450 m/min	300 m/min
Start time		7 min earlier
Extra distance covered at first		2100 m

(a)
Distance that Julian covered when he jogged 7 minutes earlier
= 7 x 300
= 2100 m

Distance that Ethan covered more than Julian per min
= 450 - 300
= 150 m

Time that Ethan needed to take to cover the additional 2100 m
= 2100 ÷ 150
= 14 min

(b)
Time that Julian would had jogged when Ethan caught up with him
= 14 + 7
= 21 min

Distance that Julian would have jogged when Ethan caught up with him
= 21 x 300
= 6300 m

Answer(s): (a) 14 min; (b) 6300 m
