Her rate of speed is 2 miles per hour.
Step-by-step explanation:
Given,
In [tex]\frac{5}{12}[/tex] hours she walks [tex]\frac{5}{6}[/tex] miles.
To find the rate of speed.
We need to find out the speed in 1 hour.
We will apply unitary method.
In [tex]\frac{5}{12}[/tex] hours she walks [tex]\frac{5}{6}[/tex] miles.
In 1 hour she walks [tex]\frac{5}{6}[/tex] ÷ [tex]\frac{5}{12}[/tex] miles.
=[tex]\frac{5}{6}[/tex] × [tex]\frac{5}{12}[/tex] miles
= 2 miles
Hence,
Her rate of speed is 2 miles per hour.
