You can put this solution on YOUR website! Along the beach, a man and a woman 1 kilometer apart walk towards each other at the same time. The man walks twice as fast as the woman. If they meet in 10 minutes, what is the rate of each person?
---
Let the woman walk at x km/minute
Then the man walks at 2x km/minute
---
The closing speed is x+2x = 3x km/min
----
Equation:
rate*time = distance
(3x)(10) = 1 km
30x = 1 km
x = (1/30) km per min (speed of the woman)
2x = 2/30 = 1/14 km per min (speed of the man)
