The midpoint of the line segment with endpoints at the given coordinates (-6,6) and (-3,-9) is 
<u>Solution:</u>
Given, two points are (-6, 6) and (-3, -9)
We have to find the midpoint of the segment formed by the given points.
The midpoint of a segment formed by 
is given by:
Plugging in the values in formula, we get,
Hence, the midpoint of the segment is
First, convert the distance of a typical marathon to kilometers.
1 mi = 1.609 km
26.2 miles = 42.165 km
Divide this distance by Allan's average speed to get his average time.
42.165 km / 12 km/hr = 3.514 hours
(2.5, 2.5) and (2, 0)
But you knew that already

12/5 is the answer!
Hope I helped!
Ps: symbolab.com is a great calculator to help solve those type of problems :-)
