The time required to empty a tank varies inversely at the rate of pumping. if a pump can empty a tank in 45 minutes at the rate of 600 gallons per minute how long will it take the pump to empty the same thing at the rate of 1000 gallons per minute

all it means is function 3

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
