<PRE><B>Question 615352</B>
Two cars are at a distance of 600 km. These are moving in opposite direction and if there is a difference of 6 km/h in their speeds and after 4 hours distance between them is 123km then find the speed of each car
**
let x=speed of slower car
x+6=speed of faster car
distance traveled=600-123=477 km
travel time=4 hrs
Distance=travel time*speed
4x+4(x+6)=477
4x+4x+24=477
8x=477-24=453
x=453/8=56.625
x+6=62.625
ans:
speed of slower car=56.625 km/hr
speed of faster car=62.625 km/hr</PRE>
