Vincent and Bobby started jogging from the same point. Bobby started jogging 9 minutes earlier than Vincent. Vincent's jogging speed was 350 m/min and Bobby'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 Vincent to catch up with Bobby? 
2. What distance would Bobby have jogged when Vincent caught up with him?  Express your answer in meters.

	Vincent	Bobby
Speed	350 m/min	200 m/min
Start time		9 min earlier
Extra distance covered at first		1800 m

(a)
Distance that Bobby covered when he jogged 9 minutes earlier
= 9 x 200
= 1800 m

Distance that Vincent covered more than Bobby per min
= 350 - 200
= 150 m

Time that Vincent needed to take to cover the additional 1800 m
= 1800 ÷ 150
= 12 min

(b)
Time that Bobby would had jogged when Vincent caught up with him
= 12 + 9
= 21 min

Distance that Bobby would have jogged when Vincent caught up with him
= 21 x 200
= 4200 m

Answer(s): (a) 12 min; (b) 4200 m
