Answer:

Her speed is 5 miles per hour.

Step-by-step explanation:

The formula of the speed is given by:

$v = \frac{d}{t}$

In which d is the distance, and t is the time.

In this question:

Distance: 1/4 mile = 0.25 miles.

Time: 1/20 hour = 0.05 hours.

So

$v = \frac{d}{t} = \frac{0.25}{0.05} = 5$

Since the distance is in miles and the time in hours, the speed is in miles per hour.

Her speed is 5 miles per hour.
