(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Two runners start simultaneously from the same point on a circular 200-m track and run in the opposite direction. One runs at a constant speed of 6.20 m/s, and the other runs at a constant speed of 5.50 m/s. when they meet, (a) for how long a time will they have been running, and (b) how far will each one have run along the track?

2. Relevant equations

3. The attempt at a solution

I could picture exactly what they our describing but I can't get the solution.

WANTS

(a)When they first meet how long atimewill each one have run along the track

and

(b)How far will each one have run along the track

*I graphed this and found the answer but I want to know if anyone could find a faster way to solving this?

(a) 17 seconds

(b) 106m , 96m

1. The problem statement, all variables and given/known data

-2 runners

-start = 0, finish = 200m

*track is circular.

*One runner is going in a negative direction

runner 1 average velocity = 6.20m/s

runner 2 average velocity = 5.50m/s

2. Relevant equations

Average Velocity = x2 - x1 / t2 - t1

where x1 is the initial position, x2 is the ending position and t1 is initial time, t2 is ending time.
