Glen and Vincent started jogging from the same point. Vincent started jogging 5 minutes earlier than Glen. Glen's jogging speed was 400 m/min and Vincent's jogging speed was 350 m/min. They went in the same direction and did not change their speeds throughout.

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

	Glen	Vincent
Speed	400 m/min	350 m/min
Start time		5 min earlier
Extra distance covered at first		1750 m

(a)
Distance that Vincent covered when he jogged 5 minutes earlier
= 5 x 350
= 1750 m

Distance that Glen covered more than Vincent per min
= 400 - 350
= 50 m

Time that Glen needed to take to cover the additional 1750 m
= 1750 ÷ 50
= 35 min

(b)
Time that Vincent would had jogged when Glen caught up with him
= 35 + 5
= 40 min

Distance that Vincent would have jogged when Glen caught up with him
= 40 x 350
= 14000 m

Answer(s): (a) 35 min; (b) 14000 m
