Question

shreya sleeps at 10:30 p.m. and get up early at 5:15 a.m. how long did she sleeps what is the steps to do

Answer 1

Solution:
To make the calculation easy, we consider a 24 hour clock.
Hence, 5:15 can be considered as 17:15 or 17.25 hours
Since Shreya sleeps at 10:30 ie, 10.50 hours

Therefore, Shreya sleeps for hours
= 17.25 - 10.50
= 6.75 hours
or we can say 6 hours 45 minutes

Hope you got it!

Answer 2

10:30-11:30=1hour
11:30-12:30=1 hour
12:30-1:30= 1 hour
1:30-2:30 =1 hour
2:30-3:30=1 hour
3:30-4:30=1 hour
4:30-5:15= 45 minutes
1+1+1+1+1+1=6 hour 45 minutes
