S_A_V [24]

Answer: D. 453 miles .

Step-by-step explanation:

Given: The function d(t)=458-60t models the distance, in miles, that Jessica is from her house <em>t </em>hours after she began returning home.

At t = 5 minutes = \dfrac{5}{60} hour     [1 hour = 60 minutes],

Distance covered by Jessica in 5 minutes = d(\dfrac{5}{60})=458-60(\dfrac{5}{60})

=458-5=453\ miles

Jessica is 453 miles from her home after 5 minutes she began returning home.

Hence, the correct option is D. 453 miles .
