How Fast Do Greyhounds Run?

Many years ago, I attended a greyhound race, and wondered how fast these fascinating dogs run.  If I were to tell you that some of the faster greyhounds can sprint as fast as 60 feet per second, do you know approximately how many miles per hour they can run?

Let's take a look at an example.

How do you convert feet per second to miles per hour?

Solution:

60 feet         60 seconds           60 minutes           1 mile            216,000
---------   x    -------------   x      -------------   x    -----------   =    ----------   =  approx. 40 miles/hr
second               minute                 hour              5280 feet           5280

To solve this problem, you need to multiply 60 x 60 x 60, which is 216,000.  One more calculation, divide 216,000 by 5280, and arrive at the answer, approximately 40 mph.

There you have it, a greyhound runs as fast as 40mph!
