Acar is traveling down a highway at a constant speed, described by the equation d=65t, where d represents the distance, in miles, that the car travels at this speed in t hours. what does the 65 tell us in this situation? *

The statement tells us that the speed is constant. Then, the equation d = 65t, is the equation of a line, whose slope is m = 65. This equation tells us that for each unit of time in hours the distance "d" increases by a constant factor of 65.

This allows to conclude that the speed of the car is 65 miles / h.

Therefore, in this situation the number 65 that appears in the equation represents the constant speed at which the car travels.

It tells us that every hour the car travels 65 miles
