Question

Mr.bonds math class starts at 11:30 if the class ends at 1:00 how long is his teaching.

Answer 1

11:30 and 1:00
assuming that it is
11:30 AM to 1:00 PM and not 11:30 AM to 1:00 AM

11:30 to 1:00 cannot be directly counted
the hours go like  this
1,2,3,4,5,6,7,8,9,10,11,12=AM
then after 12AM then
1,2,3,4,5,6,7,8,9,10,11,2=PM

60 minutes in 1 hour so
11:30=11 hours and 30 mins
how far to 12 AM?
12 AM=12 hours=11 hours and 60 minutes
11 hours and 60 minutes-(11 hours and 30 mins)=30 minutes

then from 12 AM to 1 PM=1 hour so
time total difference is 1 hour and 30 minutes

Answer 2

his class lasts for 1 hour and 30 minutes because all you have to do is count how long the hours are then subtract 30 minutes and there you go 1 hour and 30 minutes.
