Answer:
63km/hr and 70km/hr
Step-by-step explanation:
let the speed of one car be x km/hr
so the speed of the other car= -(x+7) km/hr
speed of cars wrt each other= x-{-(x+7)} km/hr =2x+7km/hr
after 2 hours
total dist - (dist covered by one car+ dist covered by another car)= 34km
300-(2x + (2x+14))=34
266= 4x+14
x=252/4=63
speed of one car = 63 km/hr
speed of other car= 70km/hr
