Question

iv) 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 speed
they meet in 5 hours. If they travel towards each other, they meet in 1 hour. What
are the speeds of the two cars?​

Answer 1

Answer:

Let the speed of car at A be x kmph

and the speed of car at B be y kmph

According to the question,

5x - 5y = 100

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

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

Solving 1 and 2 we get ,

x = 60

y = 40

Hence , Speed of the car at A = 60 kmph

Speed of the car at B = 40 kmph.

Answer 2

Answer:

speed of the car at A = 60 kmph

speed of the car at B = 40 kmph

Step-by-step explanation:

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

and the speed of car 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 kmph

speed of the car at B = 40 kmph
