Answer 2

The speed of the second car is 168 km/h.

Explanation:

It is given that, the ratio between the speeds of two cars is 5:7. Let the speed of first car is 5x and that of another car is 7x.

If the first car runs 480 km in 4 hours. The speed of first car will be,

$v=\dfrac{480\ km}{4\ h}=120\ km/h$

ATQ,

$5x=120$

x = 24 km/h

Speed of second car is 7x

i.e. v = 168 km/h

So, the speed of the second car is 168 km/h. Hence, this is the required solution.
