Bobby and Tom started jogging from the same point. Tom started jogging 7 minutes earlier than Bobby. Bobby's jogging speed was 500 m/min and Tom's jogging speed was 150 m/min. They went in the same direction and did not change their speeds throughout.

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

	Bobby	Tom
Speed	500 m/min	150 m/min
Start time		7 min earlier
Extra distance covered at first		1050 m

(a)
Distance that Tom covered when he jogged 7 minutes earlier
= 7 x 150
= 1050 m

Distance that Bobby covered more than Tom per min
= 500 - 150
= 350 m

Time that Bobby needed to take to cover the additional 1050 m
= 1050 ÷ 350
= 3 min

(b)
Time that Tom would had jogged when Bobby caught up with him
= 3 + 7
= 10 min

Distance that Tom would have jogged when Bobby caught up with him
= 10 x 150
= 1500 m

Answer(s): (a) 3 min; (b) 1500 m
