## M.Manasa 2 years ago Two cars start towards each other from points 400 miles apart. One car travels at 40 miles an hour and the other travels at 35 miles an hour. How far apart, in miles, will the two cars be after 4 hours of continuous traveling? A) 20 miles B) 40 miles C) 75 miles D)100 miles

|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?

No,I did't 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?
