Question

Rahul left the Home at 6:40 am and reached school at 7:20 am. How long did he take to reach school?

Answer 1

Hint: Here the question related to time, we have to find the time taken by Rahul to reach the school. We need to find a difference of time by subtracting the time which Rahul reached the school from the time he left home. By using the properties of time we can get the required solution.

Complete step-by-step solution:
As we know Time is an observed phenomenon, by means of which human beings sense and record changes in the environment and in the universe.
As we know time: \[1\,hr = 60\,minutes\]
Consider the given question:
Rahul left the home at 6:40 am
Rahul reached the school at 7:20 am
Therefore,
The starting time \[ = 6:40\,\,am\]
The ending time \[ = 7:20\,\,am\]
Now, find the time duration that Rahul reaches school i.e., by subtracting ending time from starting time.
\[ \Rightarrow \,\,\,7:20 - 6:40\]
Therefore, Rahul takes 40 minutes to reach school from his home.

Note: To solve this kind of problem, Add or Subtract the hours and minutes separately. But we may need to do some adjusting if the minutes end up 60 or more, or less than zero. If the minutes are 60 or more, subtract 60 from the minutes and add 1 to hours and If the minutes are negative, add 60 to the minutes and subtract 1 from hours.
