Answer 2

The speed of cars are 30 km/hr and 40 km/hr.

Step-by-step explanation:

Consider the provided information.

Let the speed of car starting from A is x km/hr.

The speed of car starting from B is y km/hr.

If they run in same direction they meet after 7 hr and the distance between point A and point B is 70 km.

That means one car need to cover 70 km in 7 hr because the distance between point A and point B is 70 km.

Then the difference of speed must be: $\frac{70}{7} =10$.

It means one car should be 10 km faster than the another car.

Let say Car starting from B is 10 km faster than car A.

If they run in opposite direction they meet after 1 hr.

The distance between point A and point B is 70 km.

x+y=70

Now substitute y=x+10 as one car is 10 km faster.

x+x+10=70

2x=60

x=30

Thus, the speed of cars are 30 km/hr and 40 km/hr.
