Answer: 30 minutes
Step-by-step explanation: First we can reduce the fraction 2/4 by dividing the numerator and the denominator by the greatest common factor of 2 and 4.
Since the factors of 2 are 1 and 2 and the factors of 4 are 1, 2, and 4, the greatest common factor of 2 and 4 is 2. So we divide the numerator and the denominator of 2/4 by 2 and we get the equivalent fraction 1/2.
Now we can change the question to say <em>1/2 of an hour is how many minutes?</em>
We know that 1 hour is equivalent to 60 minutes so half of 1 hour would be 30 minutes.
Therefore, 2/4 of an hour is 30 minutes.
