The first is a. you can rewrite it
the second is d. the only common factor between 20 and 40 that can be taken out is the 4 which becomes a 2, but inside the square roots there is still a 5 and 10, which cannot be combined
the third is c.
the fourth is d.
add 3 to both sides
then square both sides
then divide both sides by 2, x=50

The rate that is equivalent to the rate Paula walked is 1/20 mile/minute OR 0.05 mile/minute
<h3>Calculating Rate </h3>From the question, we are to determine the rate which is equivalent to the rate Paula walked
Using the formula,
From the given information,
Distance = 1/12 mile
Time = 5/3 minutes
Putting the parameters into the formula, we get
mile/minute
Hence, the rate that is equivalent to the rate Paula walked is 1/20 mile/minute OR 0.05 mile/minute
