correct answer please....​

Answer 1

Step-by-step explanation:

Let the car be A & B

Given is

Let the speed of car A be x km/h

So speed of car B = x+7 km/h

Now distance moved by them in 2 hrs:

Car A = x×2 or 2x km (S×T = D).

Car B = (x+7)×2 or 2x + 14 km

Now ATQ:

2x+14+2x+34 = 300

4x = 300-48

x= 252/4 or 63

Speed of Car A = x or 63 km/h

Speed of Car B = x+7 or 63+7 or 70 km/h

HOPE IT HELPS YOU.
