4.) 330*180 = x
x/60 = # hours
5.) seconds in a minute*minutes in an hour*hours in a day*days in a year
60*60*24*365
6.) Refer to #'s 1-3
7.) Drops - divide 355 by the number of drops in a ml
Cubic meters - 1ml = 1cm^3, 1m^3 = 1,000,000cm^3
355ml = 355cm^3 = 355/1,000,000m^3
8.) Find out how many seconds are in a day.
seconds in a minute*minutes in an hour*hours in a day
60*60*24
9.) Use converter to convert 60 miles into meters. Divide this number by 60 to get the number of meters per minute. Divide by 60 again to get meters per second.
#meters/60/60
10.) Just divide the number of gallons in the lake by the number of gallons Chicago uses in 1 day (refer to question 8)
Hope this helps!
