At what time between 9 and 10 o'clock will the hands of a watch be together?
45 min. past 9
50 min. past 9
49 1 min. past 9
11
48 2 min. past 9
11
Answer: Option
Explanation:

To be together between 9 and 10 o'clock, the minute hand has to gain 45 min. spaces.

55 min. spaces gained in 60 min.

45 min. spaces are gained in 60 x 45 min or 49 1 min.
55 11

The hands are together at 49 1 min. past 9.
11

What to do when you take minute spaces in degrees instead of minutes?

Saranya said:   3 years ago
55 = 60 min.
45 = x.
X= 60*45\55.
X = 540/11.
X = 49 1/11 past 9.

If time is between x and y:

[x*5+angle]*(12/11) past x.

Can any one say how we can say that 49 1/11 = past 9?

@All.

θ = (11m/2) - 30h is a standard formula.
