Answer:
After 6 days Martha biked 330 miles, while Enrico biked 290 miles.
Step-by-step explanation:
i. Martha bikes 55 miles per day.
So that after 6 days, Martha would have covered;
55 miles x 6 = 330 miles
After 6 days, Martha would have biked 330 miles.
ii. Enrico bikes 145 miles every 3 days.
Then after 6 days, Enrico would have covered;
x 145 miles
= 2 x 145 miles
= 290 miles
After 6 days, Enrico would have biked 290 miles.
After 6 days Martha biked 330 miles, while Enrico biked 290 miles.

Step-by-step explanation:
Converting to spherical coordinates, we have
On the other hand, we can parameterize the boundary of
by
with
and
. Now, consider the surface element
So we have the surface integral - which the divergence theorem says the above triple integral is equal to -
as required.
