10 laps around each day. each lap is 400 meters. how many days will it take to run 12 kilometers

3 days.

12 kilometers is 12,000 meters. 10 laps each day would be 4000 meters everyday.

first day : 4000 meters

second day : 8000 meters

third day : 12,000 meters

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
