Answer:
The number of gallons of water that flow over the waterfall in 1 day is [tex]6.45*10^{10} gallons[/tex]
Step-by-step explanation:
The number gallons [tex]N[/tex] of water that flow over the waterfall in 1 day is equal to number of gallons that flow in one second multiplied by the number of seconds in a day:
[tex]N =(7.5 *10^5gallons/sec)*(8.6*10^4sec/day)[/tex]
[tex]N = (7.5*8.6)*10^5*10^4[/tex]
[tex]N = 64.5*10^9 gallons[/tex]
[tex]\boxed{N = 6.45*10^{10} gallons }[/tex]
