<PRE><B>Question 419408</B>
Two cars are heading towards each other at a rate of 30 mi/h.
 When the cars are one mile apart, a fly takes off from the hood of one car 
traveling at a rate of 90 mi/h towards the other car. 
As soon as he reaches the other car, the fly instantly turns around and heads back towards the other car.
 If the fly continues flying back and forth between the cars, how far will the fly have flown when the two cars meet?
:
We know how fast the fly flies, so all we have to find out is how long it flies
to find how far it flies
:
Find how long (t) for the two cars to meet when they are 1 mi apart

:
30t + 30t = 1
60t = 1
t = {{{1/60}}} of an hr
:
Find the distance the fly flies: dist = speed * time
90 * {{{1/60}}} = 1.5 mi
