<PRE><B>Question 885905</B>
wo cars start from the same place traveling in opposite directions. One car travels 4 miles per hour faster than the other car. Find their speeds if after 6 hours they are 564 miles apart.
***
let x=speed of 1st car
x+4=speed of 2nd car
distance=travel time*speed
6x+6(x+4)=564
6x+6x+24=564
12x=540
x=45
x+4=49
speed of 1st car=45 mph
speed of 2nd car=49 mph</PRE>
