Question 533990: Tom gets on the elevator at the 11th floor and rides up at a rate of 57 floors per minute. At the same time, Jan gets on an elevator on the 51st floor and rides down at a rate of 63 floors per minute. If they continue traveling at these rates, at which floor will their paths cross?

You can put this solution on YOUR website! Tom gets on the elevator at the 11th floor and rides up at a rate of 57 floors per minute.
At the same time, Jan gets on an elevator on the 51st floor and rides down at a rate of 63 floors per minute.
If they continue traveling at these rates, at which floor will their paths cross?
:
find the time (t) at which this will occur
11 + 57t = 51 - 63t
57t + 63t = 51 - 11
120t = 40
t = min travel time when they meet
:
Find the floor they should meet at, using Tom's elevator
11 + = 30th floor
Check this using Jan's elevator
51 - = 30th floor
