Question

Convert 1 day into minutes.
A.720
B.1440
C.360
D.3600

Answer 1

Hint: At first we’ll find the number of hours in a day, then we will find the number of minutes in an hour to find the required number of minutes.
Now we can easily calculate a day into minutes using the data we have collected.

Complete step-by-step answer:
We know that we have 24 hours in 1 day
Therefore, the number of hours in one day $=$ 24
It is also well known that we have 60 minutes in one hour
Therefore, the number of minutes in 24 hours that is one day $=24\times 60$
$=1440$
The total number of hours in one day is equal to 1440 minutes
Option(B) is correct

Note: We can also do the question in an alternative method i.e. the in the reverse order of the above solution
It is also well known that we have 60 minutes in one hour
i.e. number of minutes in 1 hour $=60$
and we have 24 hours in a day i.e. equal to $60\times 24$ minutes
$=1440$
The total number of hours in one day i.e. 24 hours is equal to 1440 minutes
We can also conclude that the multiplication of two number follow commutative rule i.e. $a\times b=b\times a$
