The equation that relates the time, t, it takes to travel a given distance, d is d = rt
<h3>What is Speed?</h3>
This is a scalar quantity and can be defined as the magnitude of the rate of change of its position with time.
d = rt
where d is distance, r is speed or rate, t is time.
We can calculate the time by dividing the distance with the rate (speed).
t = d/r
This is why it was chosen as the most appropriate choice.

48= l*w
l= 8+w
To solve for width, substitute the value of l in the first equation so that everything is in terms of w.
Final answer: 48= (8+w)*w
A trapezoid is a rectangle.
