Two athletes run in different directions at 10 mph. One heads east and one heads south. Are their velocities the same?

Velocity is the speed of an object in a given direction.

Because the two runners are going in different directions the velocities are not the same.

Yes

Explanation:

Velocity is simply your displacement divided by your time.

Now if we break down displacement, it means how far you are from your starting position, even if their in opposite  directions, the displacement is still 10 miles from the starting point after one hour.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
