Question

Places 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 cars travel in the same direction at different speeds,
they meet in 5 hours. If they travel towards each other, they meet in 1 hour. What
are the speeds of the two carsرا |​

Answer 1

Answer:

A =60 km/h

B = 40km/h

Explanation:

let the speed of the car A be x km/h and car B be y km/h

as per the question

5x -5y =100

x-y =20....(1)

x+y =100....(2)

solving 1 and 2 we get

x=60 and y =40

therefore speed of the car A at =60km/h

and speed of the car B at =40km/h

Answer 2

Answer:

$\huge{\mathcal{\underline{\green{Answer}}}}$

Let the speed of car at A be x km/h

and the speed of car at B be y km/h

As per the question,

5x - 5y = 100

x - y = 20 ... (1)

and x + y = 100 ... (2)

Solving (1) and (2), we get,

x = 60 and y = 40

Speed of the car at A = 60 km/h

Speed of the car at B = 40 km/h
