Answer:

The speed of Car A is 40km/hr.

The speed of Car B is 30 km/hr.

Step-by-step explanation:

  Distance between A & B is 70km.

←A & ← B both travel in same direction.

when they are moving in same direction ,the speed is x-y.

if they travel towards each other →← they meet in 1 hour.

they are moving towards each other,the speed is x+y.

Distance = 70km

7(S1-S2)=70

S1-S2=10---›(i)

similarly

1(S1+S2)=70

S1+S2=70---›(ii)

Solving (i) & (ii)

2(S1)=80.

S1=80/2=40 Km/ hr.

substitute S1 in S1+S2=70

so,40+S2=70;S2=30 km/hr.

The speed of Car A is 40km/hr.

The speed of Car B is 30 km/hr.
