30 miles per hour.3,520 feet per minute.who runs faster and by how many miles per hour? There 5,280 feet in one mile

Answers

First let's convert 30 miles to feet. 

30 x 5,280 = 158400

Now let's find how many feet the first person runs per minute. 

158400/60 = 2640

The first person runs 2,640 feet per minute, and the second person runs 3,520 feet per minute.
Since the second person runs fast, let's find by how many miles per hour they're faster than the first person. 

3520-2640 = 880
How many miles is 880 feet?
5280/880 = 0.17

The second person runs faster by 0.17 miles per hour. 

Hope this helps! :)

This is what you meant right!? ^^^

I've done this Question before, so i'll Help You Then!


We 1st off, have to convert the ft/min speed into miles/hour: 

3520 feet ... 1 mile ..... 60 minutes ... 3520 x 60 miles 
-------------- x ------------- x ---------------- = --------------- 
1 minute ... 5280 feet .... 1 hour .......... 5280 hours 

= (3520 * 60) / 5280 
= 40 miles/hour 

The Correct Answer Is: 
B. The bison is 10 miles per hour faster than a deer.


Hope this Helps! Have A Wonderful Day! :)
