Angle between minute hand and hour hand of a clock at 6:10 and 7:20 are J and K respectively. What is the absolute difference (in degrees) between J and K?
Show answer & explanation
Correct answer: A
Explanation
Angle = |30H - 11M/2|
Finding the angle at 6:10
Here, H = 6 and M = 10.
Ɵ = |30(6) - (11 × 10)/2|
Ɵ = 125 degrees
Finding the angle (K) at 7:20
Here, H = 7 and M = 20.
K = |30(7) - (11 × 20)/2|
K = 100 degrees
Difference between Ɵ and K
125 - 100 = 25 degree
