Question

Suppose a car travels at a constant speed of 70 miles per hour. Use this information to answer the following. Use the formula d=rt to write a function d(t) that describes the distance the car travels as a function of time, t, in hours.

Answer 1

Answer:

The distance function is $d(t)=70\cdot t$

Step-by-step explanation:

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:

$\text{distance} = \text{rate} \times \text{ time}$

Rate is distance (given in units such as miles, feet, kilometers, meters, etc.) divided by time (hours, minutes, seconds, etc.).

We know that a car travels at a constant speed of 70 miles per hour.

So, the distance function is $d(t)=70\cdot t$, where t is hours and the distance is in miles.
