Answer:

Average distance traveled in 15 minutes = 7.5 miles

Step-by-step explanation:

Given function:

$d(t)=0.5t$

where $d$ represents average distance traveled in miles and $t$ represents time in minutes traveled.

To find the average distance traveled in $t=15$ minutes.

Solution:

In order to find the distance traveled in 15 minutes, we will input $t=15$ in the given function.

$d(15)=0.5(15)$

$d(15)=0.5\times 15$

$d(15)=7.5$ miles

Average distance traveled in 15 minutes = 7.5 miles

sukhopar [10]

Alright, so there are three answers. Start with 3, and for each question you answer, you can select three more, so it's 3*3 for two questions and so on, resulting in 3^8= 6561

This is assuming you mean <span>how many ways can you answer the test, not the question</span>
