Question

The Baldwin family walked four over five of a mile in four over nine of an hour. What is their unit rate in miles per hour?

Answer 1

Answer:  Option 'B' is correct.

Step-by-step explanation:

Since we have given that

Number of miles the Baldwin family walked is given by

$\frac{4}{5}\ miles$

Number of hours the Baldwin family walked is given by

$\frac{4}{9}\ hour$

So, we need to find the unit rate in miles per hour.

$Speed=\frac{Distance}{time}\\\\Speed=\frac{\frac{4}{5}}{\frac{4}{9}}\\\\Speed=\frac{9}{5}=1\frac{4}{5}\ mph$

Hence, Option 'B' is correct.

Answer 2

B, four-fifths over four ninths
