Steve gets on the elevator at the 11th floor of a building and rides up at a rate of 57 floors per minute. At the same time Joyce gets on an elevator on the 51st floor of the same building 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?
Choose one.
A) 19  B) 28  C) 30  D) 32  E) 44
Using Speed Formula: Speed = Distance / Time   Distance to be covered = 51-11= 
<gadget id="calculator">51-11</gadget>
<output>40</output>
40   Speed of approach= 57 + 63 floors/min   Time = 40/120 = 1/3   So Steve will cover 57x 1/3 floors in that time = 19   So he will be in   19 + 11=
