Suzanna walked two over seven of a mile in two over five of an hour. What is her unit rate in miles per hour?
The unit rate is
\(\frac{2/7}{2/5}\)
\(=\frac{2}{7}*\frac{5}{2}\)
\(=\frac{5}{7}\ mph\)
The unit rate of Suzana will be \(\frac{5}{7}\) miles per hour.
Unit rate is the ratio of two different units, with the denominator as 1.
We have,
Distance = \(\frac{2}{7}\) miles,
Time = \(\frac{2}{5}\) hours
Now,
The unit rate of Suzana = \(\frac{Distance}{Time}\)
i.e.
The unit rate of Suzana \(=\frac{\frac{2}{7} }{\frac{2}{5} }\)
We get,
The unit rate of Suzana \(=\frac{10}{14} =\frac{5}{7}\) miles per hour
Hence, we can say that the unit rate of Suzana will be \(\frac{5}{7}\) miles per hour.
