<PRE><B>Question 812599</B>
s = d / t
d = s * t
---
a = 100/15 m/sec
b = 100/14 m/sec
---
at 10 seconds:
a has run a distance of:
d = (100/15) * 10 = 66.7 meters
---
at 10 seconds:
b has only been running for 8.5 seconds and so has run a distance of:
d = (100/14) * 8.5 = 60.7 meters
---
Answer:
at 10 seconds A is ahead of B by 6 meters
