50 POINTS/ WILL MARK BRAINLIEST
Joylin’s work to solve a math problem is shown below.

Problem:
Manny walked 5 Over 16 of the distance to the library in 1/3 of an hour. If he walks at a constant rate, what is the total amount of time he will spend walking to the library?

Step 1: 5/16 divided by 1/3 = h
Step 2:
16/ 5 times 3 / 1 = h
Step 3:
48 / 5 = h
9 and 3/5 = h

What was Joylin’s first error? She switched the divisor and the dividend when creating an equation to model the problem in step 1. She replaced both the divisor and the dividend with their reciprocals when changing division to multiplication in step 2. She multiplied the two numerators and the two denominators to generate her product in step 3. She reduced the improper fraction incorrectly when getting her final answer.

i think the answer is She replaced both the divisor and the dividend with their reciprocals when changing division to multiplication in step 2.

the domain of y = cos x, y = cos 2x, and many other variations of this expression is "the set of all real numbers."   this function is defined for all x.
