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:

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..
