Tom and Harriet's table tennis game started at 5:55 P.M. and was over by 6:05 P.M. How long did their table tennis game last?
minutes
Quick solution:
since 5:55 is 5 minutes before 6:00 and 6:05 is 5 minutes after 6:00,
the time passed is simply 10 minutes.
Detailed solution:
Since the measurement of time was somehow skipped over when the
logical metric system was development, we are stuck with the same
awkward calculations as the other medieval calculations of distance, mass,
and temperature found in the US.
so ....
difference between 6:05 and 5:55
= (5 hours, 65 minutes) - (5hours, 55 minutes), [we had to "borrow" 1 hour]
= 0 hours, 10 minutes
= 0:10
or just 1 minutes.
OR
if you have a decent scientific calculator you should see a function key
called D:M:S
which represents Degree, Minutes, and Seconds
which are units of angle measurement.
Since those measurement units have the same base as our time
measurements of hours, minutes and seconds, they can be used
to add or subtract those units.
so enter the following
6
push the D:M:S key
5
push the D:M:S key
-
5
push the D:M:S key
55
=
you should see something like
0° 10' 0"
which means 0 hours, 10 minutes, 0 seconds
( A very practical use: Suppose you have a musical playlist that
shows the times of each of the songs and you want to find out how
long it would take to play your playlist. The times would be stated such
as 3:45, etc. Using this function makes the addition of the times very easy)
To determine the duration of Tom and Harriet's table tennis game, we can subtract the starting time from the ending time.
First, let's convert the starting and ending times to a comparable format, such as the number of minutes past midnight.
5:55 P.M. can be written as 12 * 60 + 55 = 715 minutes past midnight.
6:05 P.M. can be written as 12 * 60 + 5 = 725 minutes past midnight.
To find the duration, we subtract the starting time from the ending time: 725 - 715 = 10 minutes.
Therefore, Tom and Harriet's table tennis game lasted 10 minutes.
To find the duration of the table tennis game, we need to subtract the starting time from the ending time.
Starting time: 5:55 P.M.
Ending time: 6:05 P.M.
To subtract the starting time from the ending time, we can subtract the minutes and hours separately.
Minutes:
5:05 - 5:55 = 10 minutes
Hours:
6 - 5 = 1 hour
Therefore, Tom and Harriet's table tennis game lasted for 1 hour and 10 minutes.
