at what time between 1'o clock and 2'o clock the hands of the clock are opposite to each other
Answers
Answer:
Opposite = 180°
We have formula
Angle = modulus of 30*h - 11/2 * m
where h is hours and m is minutes
180 = modulus of 30*1 - 11/2 m
180 = MOD 30-11/2m
We have two cases.
CASE 1
+180 = 30-11/2 m
150 = -11/2 m
m = 150 * 2/-11
= -300/11
= -27. 3/11. minutes
Since minutes can't be negative, case 1 is false.
CASE 2
-180 = 30-11/2 m
-210 = -11/2m
210 = 11/2 m
m = 210*2/11
= 420/11
= 38. 2/11. minutes past 1
The answer is
GIVEN
Time = Between 1'O clock and 2'O clock
TO FIND
The time when hands of the clock are opposite to each other.
SOLUTION
We can simply solve the above problem as follows;
For the clock hands to make a straight line with each other, This means that the angle formed between them should be equal to 180°
The Hour hand will be at 1
And,
The minute hand should gain, 5+ 30 = 35 minutes
Spaces to hour hand.
Gains of Minute hand in 1 Hour = 55 minutes.
So, In 35 minutes,
=
Hence, The answer is
