Here,. 14 hours 20 minutes will be -. 20 minutes = 20/60 hours.

therefore, it will be (14 + 20/60) hours= (14+1/3) hours=43/3 hours. - i

5hours 20 minutes will be-

28 minutes = 28/60. hours

= 7/15 hours .

therefore, it will be,

= (5+7/15) hours

=82/15 hours. -ii

subtracting. ii. from i we get,

=. 43/3. - 82/15. hours
