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?
Answer by mananth(16946) (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
