Jack and Valen started jogging from the same point. Valen started jogging 7 minutes earlier than Jack. Jack's jogging speed was 300 m/min and Valen'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 Jack to catch up with Valen? 
2. What distance would Valen have jogged when Jack caught up with him?  Express your answer in meters.

	Jack	Valen
Speed	300 m/min	250 m/min
Start time		7 min earlier
Extra distance covered at first		1750 m

(a)
Distance that Valen covered when he jogged 7 minutes earlier
= 7 x 250
= 1750 m

Distance that Jack covered more than Valen per min
= 300 - 250
= 50 m

Time that Jack needed to take to cover the additional 1750 m
= 1750 ÷ 50
= 35 min

(b)
Time that Valen would had jogged when Jack caught up with him
= 35 + 7
= 42 min

Distance that Valen would have jogged when Jack caught up with him
= 42 x 250
= 10500 m

Answer(s): (a) 35 min; (b) 10500 m
