6 mph.

To find this, create a ratio.

2/20 = x/60

This will allow you to compare here time of twenty minutes to an hour in the same context.

Multiply 2 by 60 and divide by 20 to get the answer of 6 mph.

Thus, Sabrina's average speed in miles per hour is six miles per hour.

Hope this helps!

The correct answer is:  [C]:  " 5 " .
__________________________________________________________
                                →  " a = 5 " .
__________________________________________________________
Explanation:
__________________________________________________________ 

Given:  " a + 1 <span>− 2 = 4 " ; Solve for "a" ; 

4 + 2 = 6 ; 

6 </span>− 1 = 5 ;   →  a = 5 ;

To check our work:

5 + 1 − 2 = ? 4 ?? ;  

5 + 1 = 6 ; 

6 − 2 = 4.  Yes!

So the answer is:  [C]:  " 5 ".

A pump fills a pool at the rate of 20 cubic meters in an hour. If each cubic meter of water costs $10, how many minutes will the
fomenos

The first thing any good mathematician does is convert the measurements to the same unit as what the question is asking. In this problem, it states that the pool fills at a rate of 20 cubic meters per hour. Just keep in mind that an hour is 60 minutes.

The next step is to see how many cubic meters will cost $300. This can be done by dividing 300 by 10. This gets you 30 cubic meters of water.

You already know that 60 minutes is 20 cubic meters of water. That leaves the remaining 10 cubic meters of water. By dividing the rate given, you get that 30 minutes is 10 cubic meters of water. Add the 60 and 30 together to get 90 minutes.

It will take 90 minutes for the pump to use $300.
