elapsed time is 2hr 37min, end time is 10:52P.M., what is the start time?
Subtraction is key!
10:52 - 2:37 = ____ AM?
Solve it to find the answer.
I'm sorry
10:52 - 2:37 = ____ PM
PM not AM :)
6 hours and 9 minutes i think. if i got the answer wrong its because i don't know how to elapse time
start time:11:00
elapsed time:4 hours 5 minutes
end time:__________________
To find the start time, we need to subtract the elapsed time from the given end time. Here's how you can do it:
1. Convert the given end time, 10:52 PM, into a 24-hour format. To convert it, add 12 to the hour if it is PM. In this case, 10 PM would become 22:52.
2. Now, we subtract the elapsed time from the end time. Convert the elapsed time, which is 2 hours and 37 minutes, into just minutes. Multiply the hours by 60 and add it to the minutes.
Elapsed time = 2 hours + 37 minutes = 2 x 60 + 37 = 120 + 37 = 157 minutes.
3. Subtract the elapsed time from the end time:
Start time in minutes = End time in minutes - Elapsed time = 22:52 - 157.
4. Calculate the hours and minutes of the start time:
Start time hours = Start time in minutes ÷ 60 = 22 (quotient).
Start time minutes = Start time in minutes % 60 = 52 - 157 % 60 = 15.
5. Finally, convert the start time back to a 12-hour format if needed. If the start time is greater than or equal to 12, subtract 12 from the hours and add "AM" or "PM" accordingly.
Therefore, the start time is 10:15 PM.
