Question

Blake Burns four and a half calories in two thirds of a minute riding his bike what is Blake's unit rate

Answer 1

This question is asking us the unit rate, so we need to make a proportion.

$\frac{4.5}{2/3} = \frac{x}{1 minute}$

When we solve it, we end up with:

4.5 = 2/3x

And now you substitute:

$\frac{4.5}{2/3} = \frac{2/3x}{2/3}$

And you end up with your answer:

Blake burns 3/4 calories per minute.
