James knows that when h walks, he takes about 120 steps per minute and that each step is 2.75 feet long. Which calculation is most reasonable for James to use to find out his walking speed in miles for hour?

120*2.75*60/5280

= 3.75

Step-by-step explanation:

So James is walking at 120 steps a minute, there are 60 minutes in one hour, and 5,280 feet in a mile. So, to find how quickly James is walking, we multiply how many steps he is taking a minute by how much distance each step is (120 * 2.75) that gives us how much distance in one minute, so we then multiply by 60 because there are 60 minutes in one hour. Then divide the entire equation by how many feet are in one mile (5,280) giving us the answer 3.75 miles per hour. And the equation 120*2.75*60/5280

120 steps/1 minute • 2.75 feet/1 step • 1 mile/5,280 feet • 60 minutes/1 hour
