Answer: 420 (miles)

Step-by-step explanation:

Given: A car is traveling on a highway. The distance (in miles) from its destination and the time (in hours) is given by the equation :

[tex]d=420-65t[/tex]

To calculate the d- intercept of the line, substitute t =0 in the given equation , we get

[tex]d=420-65(0)\\\\\Rightarrow\ d=420=65-0\\\\\Rightarrow\ d=420[/tex]

Hence, the  d-intercept of the line is 420 (miles).
