Question

On average, a human drinks 40,000 gallons of water in their lifetime. In comparison, Lake Ontario holds approximately 8,000,000,000,000 gallons of water. Assuming that the Lake does not get replenished, how many humans would it take to drink all the water in Lake Ontario in a lifetime?

Answer 1

All you have to do is 8,000,000,000,000÷ 40,000 which is equal to 200,000,000
