Dear Student,

Please find below the solution to the asked query:

We know : Hour hand makes total angle in one revolution ( In 12 hour ) =  360° , So

Hour hand makes angle in 1 hour  =  360°12 = 30°

1 ) As hour hand move from 5 to 12 , so that cover total hours  =  12 - 5 = 7

Then,

Hour hand makes angle in 7  hour =  7 × 30°  =  210° 

We know : One right angle = 90° 

And we can see that :  210° > 90°

So,

Yes, Revolution of the hour hand more than 1 right angle .


2 ) As hour hand move from 5 to 7, so that cover total hours  =  7 - 5 = 2

Then,

Hour hand makes angle in 2  hour =  2 × 30°  =  60°                   ( Ans )

We know : One right angle = 90° 

And we can see that :  60° <  90°

So,

Angle does not moved more than 1 right angle .
