94.666666666666km por hora

Step-by-step explanation:so mark viajo a 65km we multiplica por las horas (3) lo que da 195 esto se le resta a la distancia de separación (479) el resultado es 284km(esto lo recorrio Shawn en 3 horas )y si dividimos 284 entre 3 da 94.666666 km por hora.

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
