Question

The distance between two towns is 300 km. Two cars start simultaneously from
these towns and move towards each other. The speed of one car is more than the
other by 7 km/hr. If the distance between the cars after 2 hours is 34 km, find the
speed of the cars.
​

Answer 1

Answer:

Speed of the Cars=63 km/hr

Step-by-step explanation:

Given:

The distance between two towns=300km

Speed of one car is more than the

other by 7 km/hr

the distance between the cars after 2 hours is 34 km

To Find:

Speed of the Cars=?

Solution:

Let the speed of Car A=x km/hr

Let the speed of Car B=(x+7)km/hr

From given

Distance travelled by car A after 2 hours=2x km

Distance travelled by car B after 2 hours

=2(x+7)

=(2x+14)km

Distance between the two cars after 2 hours

=300-2x-(2x+14)=34 km...............(1)

Equation (1) is written as

=4x=252

=x=252/4

=x=63 km/hr

Hence,

Speed of the cars=63 km/hr
