Let's assign variables
The time required to <span>wire a building: y
</span>
The number of electricians <span>to have done this job: x
</span>
<span>y varies inversely as x
so that:
where k is the proportional constant
To calculate the value of k, plug in the values of x and y:
x=7
y=4
Now, write down the relation between x and y:
"</span><span>how long would it have taken 3 electricians to have done the job?"
x=3
Let's find out y:
So it would take 9 hours and 20 minutes to have this job done.
