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. Plz solve it. The answer of the question is 63 km/hr​

Answer 1

Answer:

Step-by-step explanation:

Let speed of car-A = x km/hr and speed of another car-B = (x+7) km/hr

 

after 2 hours, distance travelled by car-A = 2x km

after 2 hours, distance travelled by car-B = 2(x+7) = (2x+14)  km

 

distance between the two cars after  2 hour = 300 -2x -(2x+14) = 34 km  .........(1)

 

Eqn.(1) is written as ;  4x = 252    or   x = 63 km/hr

 

Hence speed of cars, 63 km/hr and 70 km/hr
