Neave and Tommy started jogging from the same point. Tommy started jogging 4 minutes earlier than Neave. Neave's jogging speed was 250 m/min and Tommy'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 Neave to catch up with Tommy? 
2. What distance would Tommy have jogged when Neave caught up with him?  Express your answer in meters.

	Neave	Tommy
Speed	250 m/min	200 m/min
Start time		4 min earlier
Extra distance covered at first		800 m

(a)
Distance that Tommy covered when he jogged 4 minutes earlier
= 4 x 200
= 800 m

Distance that Neave covered more than Tommy per min
= 250 - 200
= 50 m

Time that Neave needed to take to cover the additional 800 m
= 800 ÷ 50
= 16 min

(b)
Time that Tommy would had jogged when Neave caught up with him
= 16 + 4
= 20 min

Distance that Tommy would have jogged when Neave caught up with him
= 20 x 200
= 4000 m

Answer(s): (a) 16 min; (b) 4000 m
