Question

at what time between 4 and 5 in the morning will the hands off a clock coincide?

Answer 1

Answer:

So the time of coincide between 4 a.m to 5 a.m is 4:21:81 ≅ 4:22

Step-by-step explanation:

Hey Mate,

The hands of a clock coincide 11 times in every 12 hours

At 4 o'clock, the minute hand is 20 min. spaces apart from the hour hand.

To be coincident, it must gain 20 min. spaces.

55 min. are gained in 60 min.

15 min. are gained in (60 x 15)/55 min = 21.81 min.

The hands are coincident at 21.81 min.

So,

The time of coincide between 4a.m to 5a.m is 4:21:81 ≅ 4:22
