Answer 2

Answer:

$\huge{\boxed{\rm{\red{Answer:-}}}}$

Let the speed of 1st car be x km/hr.

speed of 2nd car=(x+7) km/hr

Distance covered by one car in 2 hours=2x km

Distance covered by the other car in 2 hours=2(x+7)

As per the condition,

2x+2(x+7)=300-34

➪2x+2x+14=266 ➪4x=266-14

➪4x=252 ➪x=252/4=63

Hence, the speed of 1st car ➪63km/hr

and The speed of 2nd car ➪63+7=70km/hr
