Step-by-step explanation:
Answer:
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
To find the average of a set of numbers, we need to add up all of the numbers and divide by the amount of numbers we added.
Finding the average:
total = 2.5 + 4.6 + 6.75 + 4.8
total = 18.65
number of values added together = 4
average = 18.65 / 4
average = 4.66
The average distance Isabella ran is 4.66 miles.
Hope this helps!! :)
