Question

Places A and B are 100 km apart on a highway. One car starts fromA 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 cars?​

Answer 1

Step-by-step explanation:

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.

We have to find the speed of the two cars.

Solution:

We know that,

×

=

Time.

Speed

Distance

Distance between the two places A and B

=100 km

.

Let the speed of the first car starting from A be

x km/hr

and the speed of the second car starting from B be

y km/hr

.

158630-40309-1614598529

Let the cars meet at point P when they are moving in the same direction and at point Q when they are moving in the opposite direction.

When they travel in the same direction, they meet in 5 hours.

Distance travelled by the first car in 5 hours

AP=5×x km=5x km

.

Distance travelled by the second car in 5 hours

Answer 2

Answer:

Y=40

therefore the speed of the first car is 60km/hr and speed of the second car is 40km/hr
