Correct Answer

Explanation


The speed of one car is 5X km/hr, and the speed of the other car is 8X km/hr. 

The speed of the first car is 100 km/hr.

To find the value of X, we can set up the following equation: 5X = 100
Solving for X, we get: X = 100/5 = 20

The speed of the second car is 8X km/hr, so it is 8 * 20 = 160 km/hr.
