it is now 2.00 pm and 15 minutes, what fraction of a whole turn did the minute hand make? what size of the angle in degrees made by the minute hand?
15 is 1/4 of the way around to 60 min
360/4 = 90
ok what is the working and what is 360/4=90 means
/ means divide
I want to now the answers
To determine the fraction of a whole turn made by the minute hand at 2:15 pm, we need to understand that a complete revolution or whole turn is equivalent to 360 degrees.
Let's break it down:
1. Find the total number of minutes from 2:00 pm to 2:15 pm:
15 minutes.
2. Convert the minutes to a fraction of a whole hour:
There are 60 minutes in an hour, so 15/60 simplifies to 1/4.
3. Calculate the fraction of a whole turn by multiplying 1/4 (fraction of an hour) by 360 degrees (one full revolution):
(1/4) * 360 = 90 degrees.
Therefore, the minute hand has made a fraction of 1/4 of a whole turn and an angle of 90 degrees.
