Similarly, to convert hours to seconds, you can use the formula:

Number of hours × 3600 = Number of seconds

Practice Problems

Let's solve some practice problems to solidify our understanding of hours.

Problem 1:

Convert 3 hours to minutes.

Using the conversion formula:

3 hours × 60 = 180 minutes

Therefore, 3 hours is equal to 180 minutes.

Problem 2:

Convert 4.5 hours to minutes.

Solution

Using the conversion formula:

4.5 hours × 60 = 270 minutes

Therefore, 4.5 hours is equal to 270 minutes.

Problem 3:

Convert 2.75 hours to minutes.

Solution

First, convert 0.75 hours to minutes:

0.75 hours × 60 = 45 minutes

Then, add this to the 2 hours:

2 hours × 60 = 120 minutes
Total = 120 minutes + 45 minutes = 165 minutes

Therefore, 2.75 hours is equal to 165 minutes.
