Riordan and Asher started jogging from the same point. Asher started jogging 7 minutes earlier than Riordan. Riordan's jogging speed was 300 m/min and Asher's jogging speed was 200 m/min. They went in the same direction and did not change their speeds throughout.

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

	Riordan	Asher
Speed	300 m/min	200 m/min
Start time		7 min earlier
Extra distance covered at first		1400 m

(a)
Distance that Asher covered when he jogged 7 minutes earlier
= 7 x 200
= 1400 m

Distance that Riordan covered more than Asher per min
= 300 - 200
= 100 m

Time that Riordan needed to take to cover the additional 1400 m
= 1400 ÷ 100
= 14 min

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

Distance that Asher would have jogged when Riordan caught up with him
= 21 x 200
= 4200 m

Answer(s): (a) 14 min; (b) 4200 m
