Kali runs 10 laps around a track each day. each lap around the track is 400 meters. how many days will it take kali to run a total of 12 kilometers. meee]

3 days

Step-by-step explanation:

okay well first you have know how many meters are in a kilometer

1 km = 1000m

so in one day, kali runs 10 laps, 400 meters each lap:

10 × 400 = 4000 = the amount of meters she runs in a day

4000/1000 = 4 = the amount of meters she runs in a day

12/4 = 3

so it will take kali 3 days to run 12 kilometers

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
