Question

show that the minute hand of a watch gains 5 degree 30 minute on the hour hand in a minute​

Answer 1

Answer:

Since

In 60 minutes the hour hand complete 1/12 of 360°

So

60 minute = (1/12)(360°)

This implies that

60 minute = 30°

Dividing by 60 on both sides we get

1 minute = 30/60 = 1/2 = 0.5° = 30 minutes

So in one minute hour hand of the watch turns 0.5°

Since there are 5 partitions between any two consecutive number on the watch.

So when

Hour hand is on first partition then

the minute hand will be on 1/5 of 360

That is

Minute hand turns = 72 degree.
