Question

Neena is listening to a song. It has a consistent beat. She counts 11 beats in
5 seconds. What is the constant of proportionality for the relationship of beats
to minutes? Show your work.

Answer 1

Answer:

132

Step-by-step explanation:

First, find how many beats are in a minute by creating a proportion:

$\frac{11}{5}$ = $\frac{x}{60}$

Cross multiply and solve for x:

5x = 660

x = 132

So, there are 132 beats in one minute.

This means the constant of proportionality is 132.
