Question

Suppose Lin labels the books at a constant speed of s books per minute. There can be several equations written that represent 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 books per minute.

Answer 1

`S = (b)/(m)`

Explanation:

Given

`Speed = s`

Required

Determine the expression for s

The speed is calculated as:

`Speed = (Number\ of\ books)/(Time)`

Substitute S for speed

`S= (Number\ of\ books)/(Time)`

Let the number of books be b and the time be m.

The expression becomes

`S = (b)/(m)`

Hence, the expression for the scenario is:

`S = (b)/(m)`
