The rate is 1km/15min
It's a fraction where the denominator is 15 minutes.
To make it a unit rate, we need to make the denominator 1.
A unit rate would be 4 km / hour.
To find the area of a trapezoid, we use the following formula:

In this formula a represents the area and b1 and b2 each represent a base of the trapezoid.
So, we have got the following information



Filling in the formula gives us:



Finally we have to divide both sides by 15.

Therefore, the height of the trapezoid is 10 meters.
Now, if the diameter is 6 inches, then that means the radius is half that, or 3.
check the picture below.
