Question

How many minutes past \[5:00\] is \[27\]minutes before\[7:00\]?

Answer 1

Hint: Here, we will find the time which is 27 minutes before \[7:00\] by subtracting 27 minutes from \[7:00\]. Then we will subtract \[5:00\] from the obtained time to find the elapsed time. We will then convert the obtained time in minutes by adding the conversion unit to get the required answer.

Formula Used:
1 Hour \[ = \] 60 Minutes.

Complete Step by Step Solution:
We will first find the time which is \[27\] minutes before \[7:00\] by subtracting the 27 minutes from \[7:00\]. Therefore, we get
\[27\] minutes before \[7:00\] \[ = 7:00 - 0:27\]
We know that 1 hour has 60 minutes. Thus, by rewriting \[7:00\] as \[6:60\], we get
\[ \Rightarrow 27\] minutes before \[7:00\] \[ = 6:60 - 0:27\]
\[ \Rightarrow 27\] minutes before \[7:00\] \[ = 6:33\]
Now, we will find the minutes past \[5:00\] from the time which is \[27\] minutes before \[7:00\].
We will subtract \[5:00\] from \[6:33\] which is \[27\] minutes before \[7:00\], to find the minutes past \[5:00\]. Therefore, we get
Minutes past \[5:00 = 6:33 - 5:00\]
\[ \Rightarrow \] Minutes past \[5:00 = 1:33\]
The time 1 hour 33 minutes elapses between \[6:33\] and \[5:00\].
Now, we will find the time elapsed in minutes.
We know that 1 hour has 60 minutes. So,
\[1{\rm{hr}}33\min = 60 + 33\] min
Adding the terms, we get
\[ \Rightarrow 1{\rm{hr}}33\min = 93\min \]

Therefore, 93 minutes past \[5:00\] is \[27\] minutes before \[7:00\].

Note:
We should remember that while subtracting time, we will subtract hours and subtract minutes and if the minutes are negative, then add 60 to the minutes and subtract 1 from the hour. We should also remember that if the time is past, then we will find the time after the given time.
Now, we will find the minutes past \[5:00\] is \[27\] minutes before \[7:00\].
Difference between \[5:00\] and \[7:00\] \[ = 7:00 - 5:00\]
Subtracting the terms, we get
\[ \Rightarrow \] Difference between \[5:00\] and \[7:00\] \[ = 2:00\]
We know that 1 hour has 60 minutes. So,
 2 hours\[ = 2 \times 60\]
Multiplying the terms, we get
\[ \Rightarrow 2{\rm{hrs}} = 120\min \]
Now, we will subtract 27 minutes from 120 minutes to find the required answer.
\[120 - 27 = 93\min \]
Therefore, 93 minutes past \[5:00\] is\[27\] minutes before \[7:00\].
