The answer is 2 seconds.
Again, I am going to take the time to take you through a solution
step-by-step. Please read this carefully, since it is important that
you understand how to do these problems and not just know the answers.
1. There are 32 hours between noon on Monday and 8 pm on Tuesday.
2. Since the clock lost 128 seconds in these 32 hours, you can divide
128 by 32 to find out how how many seconds it lost in one hour. 128
divided by 32 is 4.
3. If the clock lost 4 seconds in an hour, then it must have lost 2
seconds in a half hour (4 divided by 2 equals 2),
One again, my strategy was to try to clearly explain the process for
solving the problem. I hope I succeeded.
