The answer to your question is letter B. h/180 is correct

Explanation:

Data

number of words = h

time = 3 hours

Process

1.- Convert the number of hours to minutes using proportions, we know that 1 hour equals 60 minutes.

1 hour ------------------- 60 minutes

3 hours ---------------- x

x = (3 x 60) / 1
