Question

What is the angle between the minute hand and hour hand at time 45 minutes past 7’O clock?

• A. 37(2/3) Degree
• B. 38(1/2) Degree
• C. 37(1/2) Degree
• D. 36(1/2) Degree

Answer 1

Answer:

C. 37(1/2) Degree

Solution: To find the angle between hour hand and minute hand, when minute hand is ahead of the hour hand. We use formula The formula is, = 30((M/5) – H) – (M/2) = 30((45/5) – 7) – (45/2) = 30( 9 – 7) – (45/2) = 60 – (45/2) = (120 – 45)/2 = 75 / 2 = 37(1/2) Degree Hence, the angle between the minute hand and hour hand at time 45 minutes past 7’O clock is 37(1/2) Degree Note: You may use the following formula: angle = 30H - (11/2)M where H = hours and M = minutes.
