length and
​

Answer 1

Answer:

63km/hr and 70km/hr

Step-by-step explanation:

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

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

after 2 hours, distance travelled by car-B=2(×+7)=

(2×+14) km

distance between the two cars after 2 hours=300-2×-(2×+14)=34 km

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

HENCE SPEED OF CARS = 63km/hr AND 70km/hr
