Conversion of Hours into Minutes

We will discuss here about the conversion of hours into minutes. We know 1 hour is equal to 60 minutes which is required to convert the measuring time from hours to minutes.

Can you tell me who plays more?

Well, both play for the same time daily.

But how? Let us see.

We know that

                   1 hour 60 minutes

So,              3 hours = 3 × 60 minutes

                               = 180 minutes

Remember

🟢 To convert hours into minutes, multiply by 60.

🟢 To convert minutes into hours, divide by 60.

Solved Examples on Conversion of Hours into Minutes:

Let us take few examples to understand the conversion of minutes and hours.

1. How many minutes are there in 3 hours?

Solution:

Now, 1 hour = 60 minutes

So, 6 hours = 3 × 60 minutes

                 = 180 minutes

2. Convert 6 hours into minutes.

We know, 1 hour = 60 minutes

Therefore, 6 hours = (6 × 60) minutes = 360 minutes

3. Convert 18 hours into minutes.

We know, 1 hour = 60 minutes

Therefore, 6 hours = (18 × 60) minutes = 1080 minutes

4. Convert 9 hours 35 minutes into minutes.

First, we convert 9 hours into minutes and then we add 35 minutes to it.

9 hours 35 minutes = (9 × 60) minutes + 35 minutes (1 hour = 60 minutes)

                             = 540 minutes + 35 minutes = 575 minutes.

5. Convert 7 hours 49 minutes into minutes.

First, we convert 7 hours into minutes and then we add 49 minutes to it.

7 hours 49 minutes = (7 × 60) minutes + 49 minutes (1 hour = 60 minutes)

                             = 420 minutes + 49 minutes = 469 minutes.

6. Convert 7 hours 45 minutes into minutes.

1 hour = 60 minutes

7 hours = 7 × 60 minutes

            = 420 minutes

7 hours 45 minutes = 420 minutes + 45 minutes

                             = 465 minutes

Word Problems on Conversion of Hours into Minutes:

1. Anthony studied for five and half hours. How many minutes did he study?

Solution:

Here,   5 hours = 5 × 60 minutes

                       = 300 minutes

and    half hour = \(\frac{1}{2}\) of 60 minutes

                       = 60 ÷ 2

                      = 30 minutes.

So, 5 and half hours = 300 minutes + 30 minutes

                              = 330 minutes

Therefore, Anthony studied for 330 minutes.
