Question 290678: Plane A and Plane B are 500 kilometres apart and flying towards each other. If plane A is travelling at a constant speed of 240 k/m and plane B is travelling at a constant speed of 360 k/m when will the planes meet? Found 2 solutions by mananth, ikleyn:Answer by mananth(16949) (Show Source):
You can put this solution on YOUR website! let the distance they meet be x from A
time taken by A when they meet = x/240
Time taken by B when they meet = 500-x /360
These two times are the same
x/240 = 500-x / 360
360x =12000-240x
120x=12000
x=12000/120
x=100 km
100/240
=10/24 *60 = 25 minutes

Plane A and Plane B are 500 kilometres apart and flying towards each other. If plane A is travelling
at a constant speed of 240 k/m and plane B is travelling at a constant speed of 360 k/m when will the planes meet?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The solution and the answer in the post by @mananth both are incorrect.
I came to bring a correct answer.
The approaching rate of the planes is 240 + 360 = 600 kilometers per hour.
Therefore, the time before they meet each other is = of an hour, or 50 minutes. ANSWER
Solved correctly and right answer is obtained, disproving the solution by @mananth.
