Question

aw, 2018 Trun 6. A bus traveled 18 miles at a speed of 55 . variable for the function that represents this situation? A. the distance the bus traveled B. the speed of the bus C. the time that it took the bus to travel D. the type of vehicle

Answer 1

Solution

Step 1

Write an equation for the speed in the situation

$\text{Speed}=\frac{dis\tan ce}{\text{time}}$

Step 2

Define the terms and substitute them into the equation and fine the time

$\begin{gathered} \text{Speed}=\text{ 55miles per hour} \\ \text{distance = 18 miles} \\ Time=\text{ }\frac{dis\tan ce}{\text{speed}} \\ \text{Time}=\frac{18}{55}hrs \end{gathered}$

Therefore, the dependent variable for the function that represents this situation is the distance
