Answer :

To find 25% of 1 hour in minutes, follow these steps:

1. Convert 1 hour to minutes:
- Since 1 hour is equivalent to 60 minutes, we start with 60 minutes.

2. Calculate 25% of the 60 minutes:
- To find 25% of a number, you can multiply the number by 0.25 (as 25% is equivalent to 0.25 in decimal form).
- Now, multiply 60 by 0.25 to get the required percentage:
[tex]\[\text{25% of 60 minutes} = 60 \times 0.25 = 15\][/tex]

So, 25% of 1 hour is:

- 60 minutes (total minutes in 1 hour)
- 15 minutes (which is 25% of 60 minutes)

The answer is therefore 15 minutes.
