Question

Places A and B are80km apart from each other. On a highway a car starts from A and another from B at the same time. If they move in same direction they meet in 8 hours and if they move towards each other they meet in 1 hour 20 minutes. Find the speed of cars

Answer 1

A+B=80
Let their speeds be x and y
8(x-y) =80
4/3(x+y)=80
x-y=10
x+y=60
On adding both equations
2x=70
x=35km/hr
Y=25km/hr
