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

___________________________

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:

"
(48)/(1) *(3)/(2) " ;

__________________________

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

→ {Since: "48 ÷ 2 = 24 "} ;

___________________________

And we have:

___________________________

"
(24)/(1) *(3)/(1) = 24 * 3 = 72 " ;

___________________________

The answer is: " 72 words per minute ."

___________________________

Hope this is helpful to you!
