Question 389547: The horizontal distance of a kite from the boy flying it is 30 m and 50 m of cord is out from the roll. If the wind moves the kite horizontally at the rate of 5 km per hour directly away from the boy, how fast is the cord being released? Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! The horizontal distance of a kite from the boy flying it is 30 m and 50 m of cord is out from the roll. If the wind moves the kite horizontally at the rate of 5 km per hour directly away from the boy, how fast is the cord being released?

This is right triangle problem.
horizontal distance is 30m
string is 50m
the vertical distance = 40m (pythagorean triple)
kite rate horizontally = 5km/h
=5000m/3600 seconds
Hypotenuse to ground distance ratio = 5/3
String released at (5/3)*( 5000/3600)
= 2.31 m/s approximately
