What time does a 12-hour clock read
a) 80 hours after it reads 11:00?
b) 40 hours before it reads 12:00?
c) 100 hours after it reads 6:00?
Note: The time that a 12-hour clock will read after a given time period is given by the formula is
Division algorithm:If and , then there are unique integers q and r , with , such that
Here d is called the divisor.
a is called the dividend.
q is called the quotient.
r is called the remainder.
Note that the remainder is non negative , and less than the divisor.
a)In this problem we need to find that what does a 12-hour clock read after 80 hours.
Given: 80 hours after it reads 11:00
Current time = 11:00 , and number of hours = 80.
The time that a 12-hour clock will read after 80 hours
, since by the note
91 is divided by 12 means 91 = 12(7)+7 , here remainder is 7.Since...
