If two runners take the same amount of time to run a mile, they have the same
a. acceleration
b. force
c. mass
d. velocity

None of the choices is correct.

If two runners take the same amount of time to run a mile,
they have the same average speed.  But their velocities
are not the same unless both runners begin and end their
run at the same points.

Speed is   (distance covered) divided by (time to cover the distance).

Velocity is not.  It's something different. 
'Velocity' is not just a bigger word for 'speed'.

Hypothesis. why don’t you know this? i learned this stuff in like 5th grade
