unit of measurment a punk/disco band, played a benefit concert for new year's eve. they started at 7:00p.m on new year's eve and managed to play until 8:30a.m. the following morning. what is the order of magnitude of the total number of seconds they played. what do they mean by magnitude and how to solve it

phi · Answer

order of magnitude means to the nearest power of 10

First, can you find the number of hours from 7 pm to 8:30 am ?
then multiply by 60 to get minutes
then multiply by 60 again to get seconds  (or just multiply the hours by 3600)

can you do that?
once you get that number we can figure out the order of magnitude
