Question

The distance between two cities, A and B. is 70 km. Two cars start moving from A and B respectively. Ifthey move in the same direction, they will meet in 7 hours and if they move towards each other they will meet in 1 hour. Find the speeds of both the cars.​

Answer 1

Answer:

The speed is 10 KM PER HOUR

Step-by-step explanation:

Answer 2

Let the speed of the car at point A be x k m / h

Let the speed of the car at point B be y km/ h

The respective speed of the car when they are traveling in the same direction is : x - y

The respective speed of the car when they are traveling in the opposite direction is x+ y

From the given information

case 1 :

they travell in same direction and meet after 7 hours

distance between the points = 70km

:- 7 ( x - y ) = 70

:- x - y = 10 ( 1 )

case 2 :

they travell in opposite directions and meet after 1hr

1 ( x + y ) = 70 ( 2 )

solving ( 1 ) and ( 2 )

x = 40

y = 30

:- speed of car at point A = 40 km / h

:- speed of car at point B = 30 km / h
