Question

10. Julio is driving to the store. The average distance d, in miles, he travels over t minutes is given by the

function d(t) = 0.5t. What is the value of the function when t = 15?

Answer 1

7.5 miles

Explanation:

Given the equation d(t) = 0.5t, all you need to do is plug in the value of t.

They're asking what the Function equals, and they're giving you the value of the variable t.

To solve, write the equation d(15) = 0.5(15)

And if you simplify the right side of the equation, you'll find that

d(15) = 7.5

If t represents time, then you can conclude that Julio travels 7.5 miles in the time t, of 15 minutes.
