Answer: 2 2/5 distance
Step-by-step explanation:
You know 1/4 of an hour you travel of 3/5 of distance, so let’s set an proportion: 1/4 hr = 3/5 of distance, multiply 4 on both sides, and you get 2 2/5 distance. Hope this helps!
A circle is 360° , if youdivide<span> an arc's </span>degree measure<span> by 360°, you find the fraction of the circle's </span>circumference<span> that the arc</span>makes<span> up. Then, if you multiply the length all the way around the circle </span>by that fraction, you get the length along the arc.

∴ 
Stokes' theorem equates the line integral of
along the curve to the surface integral of the curl of
over any surface with the given curve as its boundary. The simplest such surface is the triangle with vertices (1,0,1), (0,1,0), and (0,0,1).
Parameterize this triangle (call it
) by


with
and
. Take the normal vector to
to be

Divide this vector by its norm to get the unit normal vector. Note that this assumes a "positive" orientation, so that the boundary of
is traversed in the counterclockwise direction when viewed from above.
Compute the curl of
:

Then by Stokes' theorem,

where



The integral thus reduces to
