To start, note that an hour is 60 minutes long. A 1/2 hour, or half hour, is then 60/2=30 minutes. Therefore, when we have 11 hours and 30 minutes, we have 11 and a half hours. Adding 3 and a half to that, we get 11.5+3.5=15 (a half can also be expressed as .5, although it's not typically done that way when expressing time - it just might be easier to visualize it this way). Therefore, we are 15 hours into the day. However, we can't just stop there - we have to account for AM and PM. Therefore, we subtract 12 hours from 15. If the number is positive, we are in PM - otherwise, we're in AM. Therefore, as 15-12=3, the time is in PM. The remaining number is the time, so Bill leaves at 3 PM. If we are left with a decimal (e.g. 3.25), we would keep the 3 and multiply the 0.25 (the decimal) by 60 to figure out how many minutes we have, so 3.25 would turn into 3+0.25*60=3:15.

Answer:
x=4
Step-by-step explanation:
Let n is the number of marbles.
when marbles are equally shared among 6, 7 or 8 students, each time 4 marbles left over.
To find the least number of marbles, first we find out what is the smallest number that can be divided to 6, 7 and 8.
Now you see that 6 and 8 are divisible by 2 but 7 is non- divisible.
if we take LCM of 6, 7 and 8 and find the smallest number.
2 I6,7,8
-------
3,7,4
Now multiply 2,3,7 and 4
2 x 3 x7 x 4 = 168
each time 4 marbles left so
least possible number of marbles in the box = 168 + 4 = 172
