Question

Suppose Clare labels the books at a constant speed of s books per minute. Write an equation that represents the relationship between her labeling speed and the number of minutes it would take her to finish labeling.

Complete the equation below:




m = _________ where m is the number of minutes and s is the speed in boo

Answer 1

The data is:

Clare labels s books per minute.

We define m as the variable that represents minutes.

Then, in m minutes, she can label m times s books.

B(m) = s*m

Now, we can suppose that the number of books that she needs to label is known, a number N. (when she labels the N books, she finishes her job)

Then the time that she will need to complete the task is:

s*m = N

Where we can isolate m as:

m = N/s.
