John is participating in a marathon that is 26 2 miles. His distance (d, in miles) depends on his time (t, in hours). Which is an appropriate range for
this situation?

0-27

Step-by-step explanation:

The range of a function is representative of the values on the y-axis. In this case, the graph will contain distance on the y-axis at is the dependent variable, while the independent variable is time.

We know that the minimum value of the distance will be 0, given that there can be no negative distance. Moreover, the maximum value is 26.2 miles, since the marathon will then be over. Therefore, a good range for the situation will be 0-27 miles.

I hope this helps. I am sorry if you get this wrong.
