Amule dear can 1/4 of a mile in 25 seconds. at this rate, what expression can be used to determine how fast a mule deer runs in miles per hour

We have to find how many seconds are in one hour.
There are 60 seconds in one minute, with 60 minutes in every hour.
60×60=3600
Now, see how many 25 seconds are in 3600 seconds.
3600÷25= 144
Now, we can multiply 144 by 14 or .25 since we are trying to find per hour.
144×.25= 36
36h
H being the hours you're trying to find. It runs 36 miles per hour.

Number nine is f(x)= 40x : ) hoped i ya
