<h2><em>Answer:
</em></h2><h2><em></em></h2><h2><em>The distance function is d(t)=70.t</em></h2><h2><em></em></h2><h2><em>Step-by-step explanation:
</em></h2><h2><em></em></h2><h2><em>If an object moves at a constant rate of speed, we can determine how far the object travels by multiplying its rate by the time it has been traveling:
</em></h2><h2><em></em></h2><h2><em>
distance=rate X time</em></h2><h2><em></em></h2><h2><em>Rate is distance (given in units such as miles, feet, kilometers, meters, etc.) divided by time (hours, minutes, seconds, etc.).
</em></h2><h2><em></em></h2><h2><em>We know that a car travels at a constant speed of 70 miles per hour.
</em></h2><h2><em></em></h2><h2><em>So, the distance function is ,d(t)=70.t where t is hours and the distance is in miles</em>.</h2>
