Answer:
He needs to run 7 miles per day. 217/31 = 7m
Step-by-step explanation:
<span>The partial derivative of the given function with respect to x is
a - by/cx2 + dy/dx
In this derivative the terms in the with x is only considered other or treated as constant
The partial derivative of the given function with respect to y is
b/cx+ d2y/dx.
In this derivative the terms in the with x is only considered other or treated as constant</span>
If the first gardener can finish the job in 6 hours, it means that every hour he completes 1/6 of the job.
By the same logic, the second gardener completes 1/7 of the job per hour.
So, if they work together, they complete

of the job per hour.
So, after 42/13 of a hour, they'll complete the job. Since one hour is made of 60 minutes, 42/13 of a hour is

So, it will take them about 194 minutes to finish the job, i.e. about 3 hours and 14 minutes.
