please help me fast​

Answer 1

let speed of car which starts from A be x km/h and from B be y km/h.

Case 1: when they move in same direction :

Distance covered by A - Distance covered by B=80 km

8(x-y)=80

x-y=10 -(1)

Case 2 :When they move in opposite durection

Distance covered by A + Distance covered by B

4/3(x+y)= 80

x+y=60 -(2)

By solving equation (1) and (2)

x=35 km/h

y=25 km/h
