Bobby and Eric started jogging from the same point. Eric started jogging 9 minutes earlier than Bobby. Bobby's jogging speed was 500 m/min and Eric'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 Bobby to catch up with Eric? 
2. What distance would Eric have jogged when Bobby caught up with him?  Express your answer in meters.

	Bobby	Eric
Speed	500 m/min	250 m/min
Start time		9 min earlier
Extra distance covered at first		2250 m

(a)
Distance that Eric covered when he jogged 9 minutes earlier
= 9 x 250
= 2250 m

Distance that Bobby covered more than Eric per min
= 500 - 250
= 250 m

Time that Bobby needed to take to cover the additional 2250 m
= 2250 ÷ 250
= 9 min

(b)
Time that Eric would had jogged when Bobby caught up with him
= 9 + 9
= 18 min

Distance that Eric would have jogged when Bobby caught up with him
= 18 x 250
= 4500 m

Answer(s): (a) 9 min; (b) 4500 m
