Asher and Tommy started jogging from the same point. Tommy started jogging 4 minutes earlier than Asher. Asher's jogging speed was 500 m/min and Tommy's jogging speed was 100 m/min. They went in the same direction and did not change their speeds throughout.

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

	Asher	Tommy
Speed	500 m/min	100 m/min
Start time		4 min earlier
Extra distance covered at first		400 m

(a)
Distance that Tommy covered when he jogged 4 minutes earlier
= 4 x 100
= 400 m

Distance that Asher covered more than Tommy per min
= 500 - 100
= 400 m

Time that Asher needed to take to cover the additional 400 m
= 400 ÷ 400
= 1 min

(b)
Time that Tommy would had jogged when Asher caught up with him
= 1 + 4
= 5 min

Distance that Tommy would have jogged when Asher caught up with him
= 5 x 100
= 500 m

Answer(s): (a) 1 min; (b) 500 m
