Answer:
r = 3.5 acre/hour
Step-by-step explanation:
Rate of Change
Farmer Fran had harvested 2 acres of pomegranates at 10:00 A.M. At noon (12:00 P.M.) she had harvested 9 acres.
From both times, 2 hours had passed. During that time, she harvested 9-2=7 acres.
The rate of harvesting is:
[tex]r=\frac{7}{2}\ acre/hour[/tex]
Or, expressed in decimal:
r = 3.5 acre/hour
