Question 942376: Two runners approaching each other on a straight track have constant speeds of 4.50 m/s and 3.50 m/s, respectively, when they are 100 m apart. How long will it take for the runners to meet, and at what position will they meet if they maintain these speeds? Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! speed of runners relative to each other:
4.50 + 3.50 = 8 m/s
---
s = d/t
t = d/s
t = 100/8
t = 12.5 seconds
---
position of fast runner at the meet:
d = st
d = 4.5 * 12.5
d = 56.25 m from his initial position
---
position of slow runner at the meet:
d = st
d = 3.5 * 12.5
d = 43.75 m from his initial position
