Commuter trains depart from North Station every 10 minutes. Subway trains depart every 3 minutes. A subway train and a commuter train both leave the station at 8:15. How long will it be before the subway trains and the commuter trains depart again at the same time? What time will that be?

it would be 6xy and -16xy.

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

1st part is 64,000,000

2nd part 500,000
