Zane and Bobby started jogging from the same point. Bobby started jogging 10 minutes earlier than Zane. Zane's jogging speed was 350 m/min and Bobby'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 Zane to catch up with Bobby? 
2. What distance would Bobby have jogged when Zane caught up with him?  Express your answer in meters.

	Zane	Bobby
Speed	350 m/min	250 m/min
Start time		10 min earlier
Extra distance covered at first		2500 m

(a)
Distance that Bobby covered when he jogged 10 minutes earlier
= 10 x 250
= 2500 m

Distance that Zane covered more than Bobby per min
= 350 - 250
= 100 m

Time that Zane needed to take to cover the additional 2500 m
= 2500 ÷ 100
= 25 min

(b)
Time that Bobby would had jogged when Zane caught up with him
= 25 + 10
= 35 min

Distance that Bobby would have jogged when Zane caught up with him
= 35 x 250
= 8750 m

Answer(s): (a) 25 min; (b) 8750 m
