the endpoints of a line segment are at the coordinates (-6,3,4) and (4,-1,2). what is the midpoint of the segment?

answer options:
(-10,-2,2)

(-5,-1,1)

(-2,2,6)

(-1,1,3)

(-1,1,3)

Step-by-step explanation:

midpoint = (x1+x2/2, y1+y2/2, z1+z2/2)

midpoint = ( (-6+4)/2, (3+-1)/2, (4+2)/2 )

midpoint = (-2/2, 2/2, 6/2)

midpoint = (-1, 1, 3)

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s
