C) 4
Step-by-step explanation:
Given equation:
The above equation represents proportional relationship.
To find the constant of proportionality.
Solution:
<em>The equation representing proportional relationship is given by:</em>
<em></em>
<em>where represents constant of proportionality.</em>
So, in order to find the value of for the given proportionality relationship, we will solve for
We have:
Solving for
Dividing both sides by 2.
∴
Thus, the constant of proportionality = 4.
We use the formula where d is distance, s is speed and t is time.
Therefore, a car would tracel 480 km.
