Question

wyatt can husk at least 12 dozen ears of corn per hour and at most 18 dozen ears of corn per hour. Based on this information. what is a possible amount of time, in hours, that it could take wyatt to husk 72 dozen ears of corn?

Answer 1

If Wyatt can husk at least 12 an hour, then to work out how much 72 takes, we do 72 ÷ 12 to find out the time. The answer is 6.

If Wyatt can husk 18 at most, then we do 72 ÷ 18 = 4 hours.

Wyatt can husk 72 dozen ears in anywhere between 4 and 6 hours, but if you were to average it, you would get 5 hours. ((4 + 6) ÷ 2 = 5).

Answer 2

so a possible amount of time
find the range of highest and lowest
equation is
(number of corns per hour) times (number of hours)=72
so
12 times x=72 would be longest and
18 times y=72 would be shortest

solve
12 times x=72
divid 12
x=6
6 hours at most

18 times x=72
divide 18
x=4

at most 6 hours an at least 4 hours so
6>hours>4
any number of hours from 4 to 6 including 4 and 6
