Warren and Oscar started jogging from the same point. Oscar started jogging 4 minutes earlier than Warren. Warren's jogging speed was 450 m/min and Oscar'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 Warren to catch up with Oscar? 
2. What distance would Oscar have jogged when Warren caught up with him?  Express your answer in meters.

	Warren	Oscar
Speed	450 m/min	350 m/min
Start time		4 min earlier
Extra distance covered at first		1400 m

(a)
Distance that Oscar covered when he jogged 4 minutes earlier
= 4 x 350
= 1400 m

Distance that Warren covered more than Oscar per min
= 450 - 350
= 100 m

Time that Warren needed to take to cover the additional 1400 m
= 1400 ÷ 100
= 14 min

(b)
Time that Oscar would had jogged when Warren caught up with him
= 14 + 4
= 18 min

Distance that Oscar would have jogged when Warren caught up with him
= 18 x 350
= 6300 m

Answer(s): (a) 14 min; (b) 6300 m
