    |dw:1352546945270:dw| The cars travel towards each other at 40 miles/h and 35 miles/h So the distance between them reduces at a speed of (40+35) mile/s After two hours the distance between them will be reduced by \[2\times(40+35) miles\] Do you get this?

    Suppose Only one car is moving, the other is stationary. Distance between them is 400 miles Distance will reduce at a speed of the moving car. Do you get this?
