Approximately 75 times 103 gallons of water flow over a wate

Approximately 7.5 times 10^3 gallons of water flow over a waterfall each second. There are 8.6 times 10^4 seconds in 1 day. Select the approximate number of gallons of water that flow over the waterfall in 1 day. 6.45 times 10^21 6.45 times 10^20 6.45 times 10^10 6.45 times 10^9

Solution

Gven that

Approximately 7.5 x 10⁵ gallons of water flow over a waterfall each second

There are 8.6 x 10⁴ seconds in 1 day

Water flow over a waterfall in 1 day =  8.6 x 10⁴ seconds x 7.5 x 10⁵ gallons per second

= 8.6 x 10⁴ x 7.5 x 10⁵ gallons

= 6.45 x 10¹⁰ gallons

Therefore,

Water flow over a waterfall in 1 day =   6.45 x 10¹⁰ gallons
