There are 60 minutes in an hour. How many minutes are there in a day (24 hours)?

• A. 270
• B. 2700
• C. 3500
• D. 1440

Answer 1

The correct option is D 1440

Number of minutes in an hour = 60
Number of minutes in 24 hours = ?

= 24 x 60

In order to multiply by a number ending in zeros, we first need to multiply the number as if it didn't have zeros, and then we just write all of the zeros the number had, on the right of the final answer.

So, at first, we calculate 24 x 6.

24
x 06
______

Then, 24 x 60 = 1440

Therefore, there are 1440 minutes in 24 hours.
That is, there are 1440 minutes in a day.
