Billy and Glen started jogging from the same point. Glen started jogging 4 minutes earlier than Billy. Billy's jogging speed was 300 m/min and Glen's jogging speed was 250 m/min. They went in the same direction and did not change their speeds throughout.

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

	Billy	Glen
Speed	300 m/min	250 m/min
Start time		4 min earlier
Extra distance covered at first		1000 m

(a)
Distance that Glen covered when he jogged 4 minutes earlier
= 4 x 250
= 1000 m

Distance that Billy covered more than Glen per min
= 300 - 250
= 50 m

Time that Billy needed to take to cover the additional 1000 m
= 1000 ÷ 50
= 20 min

(b)
Time that Glen would had jogged when Billy caught up with him
= 20 + 4
= 24 min

Distance that Glen would have jogged when Billy caught up with him
= 24 x 250
= 6000 m

Answer(s): (a) 20 min; (b) 6000 m
