John typed a 48 word paragraph in 2/3 minute. What is the typing speed in words per minute​
serg [7]

Answer:  The answer is:  " 72 words per minute. "

___________________________

Step-by-step explanation:

___________________________

This is a "unit rate" problem.

We want to solve for/ find the number of words PER single minute.

___________________________

Given 48 words per (2/3) minute;

How many words per (one) minute?

__________________________

The answer is {48 ÷ (2/3) } words per minute:

 Note: dividing by a number is the same as multiplying by the reciprocal (inverse) of that particular number:

Hence:

__________________________

The answer is {48 * (3/2) } words per minute:

__________________________

 Write as:

  " \frac{48}{1} *\frac{3}{2} " ;

__________________________

  The "48" can be changed to "24" ; and the "2" can be changed to "1" ;

   → {Since: "48 ÷ 2 = 24 "} ;

___________________________

And we have:

___________________________

  " \frac{24}{1} *\frac{3}{1} = 24 * 3 = 72 " ;

___________________________

The answer is:  " 72 words per minute ."

___________________________

Hope this is helpful to you!
