Question

#1) Write the ratio of 60 km in 28 minutes in simplest form.#2) Is this ratio a rate? Explain your answer using words. [C

Answer 1

1. Expressing 60km per 28 minutes in its simplest form requires us to get it per 1 minute. This, we can easily obtain by:

$\frac{60\operatorname{km}}{28\min}=\frac{15\operatorname{km}}{7\min}=2\frac{1}{7}\frac{km}{\min }$

2.143 km per minute

2. The ratio is a rate. A rate is a measure of a quantity with respect to another, especially with respect to time.

As can be seen, this ratio is speed. Speed is a measure of distance covered per time.
