Answer:
60,480 is the correct answer.
Step-by-step explanation:
First of all, let us have a look at the <em>formula of factorial of a number 'n'</em>:
i.e. multiply n with (n-1) then by (n-2) upto 1.
<em>Keep on subtracting 1 from the number and keep on multiplying until we reach to 1.</em>
<em></em>
So, can be written as:
Similarly can be written as:

Now, the expression to be evaluated:
Answer:
6.96 hours.
Step-by-step explanation:
First, we need to find out the hour rate of bushels picked for each of them.
If Imani can pick 40 bushels in 15 hours, then he picks 40/15 = 8/3 bushes per hour.
If Bill can pick 40 bushels in 13 hours, then he picks 40/13 bushes per hour.
Working together, they pick: bushes per hour.
Let's simplify this expression:
= 5.74
Now we can use a rule of three
1 hour -------5.74
x hours ------40
Then,
x = 40 / 5.74 = 6.96
Therefore, it would take them 6.96 hours working together.
