Harry and Riordan started jogging from the same point. Riordan started jogging 2 minutes earlier than Harry. Harry's jogging speed was 300 m/min and Riordan'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 Harry to catch up with Riordan? 
2. What distance would Riordan have jogged when Harry caught up with him?  Express your answer in meters.

	Harry	Riordan
Speed	300 m/min	200 m/min
Start time		2 min earlier
Extra distance covered at first		400 m

(a)
Distance that Riordan covered when he jogged 2 minutes earlier
= 2 x 200
= 400 m

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

Time that Harry needed to take to cover the additional 400 m
= 400 ÷ 100
= 4 min

(b)
Time that Riordan would had jogged when Harry caught up with him
= 4 + 2
= 6 min

Distance that Riordan would have jogged when Harry caught up with him
= 6 x 200
= 1200 m

Answer(s): (a) 4 min; (b) 1200 m
