2.75/ 1.25 = 2.2 miles per hour ( or 2 and 1/5)
Hope this helps (:
For this case, what we should do is find Ammar's speed.
We have then:
Then, on the other hand we have:
1 hour = 60 minutes
Substituting values we have:
Rewriting we have:
Ammar hikes miles per hour
To makes things simpler , the fraction for miles will be converted into an improper fraction, so it will be 11/4.
For the time, there is 60 minutes in one hour, so 60 plus the 15 minutes is 75.
Now that the numbers are simpler, we can start to create cross products.
In 11/4 miles it takes 74 minutes. How many in 60 minutes ? So to find that, take 11/4 over x equals to 75 over 60. Cross multiply:
11/4 * 69 = 165
75 * x = 75x
The equation is now 75x = 165
Divide 75 in both sides to isolate variable x.
x = 2.2
2.2 in fraction form is 2 1/5 .
So finally it takes Amman to walk 2 1/5 miles per every hour.
i don't even know man. edge inuity be messing with us. i had to ask a question too.
→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.
that is, number of columns of a= number of rows of b.
so, size of matrix , c= a b is , if a = (m × n)matrix
b= (n × p)matrix
then a b = [ (m × n)matrix] ×[ (n × p)matrix ]
→→c= a b= [m × p ] matrix
→→size of product a b will be equal to = number of rows of a × number of columns of b
