Question

fhhplace A and B are 100 KM apart on a highway one car starts from A and another from B at the same time if the car travel in the same direction at different speeds they met in 5 hours if they travel towards Each Other they meet in 1 hour what are the speeds of the two car ​

Answer 1

Answer:

let speeds be x and y km/h

5x-5y=100

(÷by5) x-y=20 --------1

x+y=100 ------------2

on solving 1, 2 we get 2x=120

x=60km/h

sub x value in either equations , y=40km/h
