Question

The average amount of water flowing over Niagara Falls is 1.68 X 10^5 m^3/min.
a. How many cubic meters of water flow over the falls in one day?
b. How many cubic meters of water flow over the falls in one year?

Answer 1

1 hour = 60 min

24*1 hour = 24*60 min

24 hours = 1440 min

1 day = 1440 min

Answer 2

a)

(1.68 X 10^5 m^3/min) * (1440 min/1 day) = 1.68 X 10^5*1440 = 241,920,000 m^3/day

which converts to 2.42 x 10^8 in scientific notation

So roughly 2.42 x 10^8 cubic meters of water flow over the falls in one day
