If you travel at a constant speed, you follow this formula:

where s is the space traveled, v is the speed and t is the time passed. Knowing the speed and the desired space, we can solve the equation for the time:

Plug your values:

And two-thirds of an hour are 40 minutes.
To convert his speed in miles per minutes, you only need to use that one hour is composed of 60 minutes:
miles per minute
The circumference of a circle can be found by applying the formula 3.14*diameter. To find the area of a circle requires you to use the equation 3.14 * r^2. A change in diameter will affect the circumference. The approximate diameter of the circle 87.14 meters. This means the equation is 1854.7749*3.14, making the approximate area of the circle 5823.99319 m^2. ROund if you need to.
