Answer:

16.1 MPH

Step-by-step explanation:

If the wheels have a radius of 15 inches, then the circumference of a wheel is 2πr = 2 * π * 15 ≈  94.248 inches.

If the wheels turn at 3 revolutions per second, that mean the car is travelling 94.248 * 3 ≈ 282.74 inches/second.

There are 12*5280 = 63360 inches in a mile and 60 * 60 = 3600 seconds in an hour. So to convert from inches/second to miles per hour, we need to divide the inches per second figure by (63360/3600), which is 17.6, to get miles per hour (MPH).

So in this case, 282.74/17.6 gives you approximately 16.1 MPH.

Verizon [17]

Answer:

Both the stock have the same expected return.

Step-by-step explanation:

In year 1 the return earned by stocks A and B are:

Stock A = 2% return

Stock B = 9% return

In year 2 the return earned by stocks A and B are:

Stock A = 18% return

Stock B = 11% return

Compute the expected return for stock A as follows:

Expected\ return\ for\ A=\frac{2+18}{2}=10\%

Compute the expected return for stock B as follows:

Expected\ return\ for\ B=\frac{9+11}{2}=10\%

Thus, both the stock have the same expected return.
