Question 157232
0.04 acres/sec=0.04 *60acres/min= 2.4 acres/min------(60 sec=1 min)
2.4 acres/min=2.4*60 acres/hour=144 acres/hour (60 min=1 hour)
144 acres/hour*48 hours=6912 acres

CK 
how many seconds in 1 hour? 60*60=3600
How many seconds in 48 hours? 3600*48=172800
so, 0.04*172800=6912
6912=6912

Hope this helps---ptaylor
