Question

If the angle turned by minute hand in 15
minutes in 90', by how many straight angles
will it turn in 1 day?​

Answer 1

minute hand turns angle of 90° in 15 minutes

straight angle = 180°

to find:-

how many straight angle 180° angle are formed in one day

1 day = 24 hrs

24 hrs = 1440 mins

In 1 hour the minute hand will form 7 straight angle(180°)

1 hour = 7 times 180° angle will be formed

so to find how many 180° angles will be formed in one day by minute hand

to find it multiply

24 hrs x no of 180° angles formed in one minute

24 x 7 = 168

Therefore 168 times straight angles (180°) will be formed in one day that is 24 hrs

24hrs = 168 straight angles

may this helps you

hope this is correct answer which you want if it's not report it

only if it's wrong
