Question 884351: Two cyclists start on a circular track from a given point but in opposite directions with speeds of 7 m/sec and 8 m/sec respectively. If the circumference of the circle is 300 meters,after what time will they meet at the starting point ? Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Two cyclists start on a circular track from a given point but in opposite directions with speeds of 7 m/sec and 8 m/sec respectively. If the circumference of the circle is 300 meters,after what time will they meet at the starting point ?
--------------------------
slower cyclist DATA:
rate = 7 m/sec ; time = x sec ; distance = 7x meters
---------------
faster cyclist DATA:
rate = 8 m/sec ; rime = x sec ; distance = 8x meters
-----------
Equation:
dist + dist = 300 meters
15x = 300 meters
x = 20 seconds
