To calculate how long an impulse takes to travel a certain distance, you can use the following equation: If an impulse travels 100 m/s, about how long will it take the impulse to travel 10 meters?

The answer is choice first which is "When x = 3, both expressions have a value of 30".

Step-by-step explanation:

Given:

First expression:

Second expression:

Through the question when we substitute x=3 into its first equation so we get:

The value will be substituted by x=3 into its second expression:

So, it will prove that both the two expressions are equivalent.
