Ann walked 1.5 miles south to her house in 0.5 hours. what is ann's speed? what is ann's velocity

To calculate the speed and velocity of the Ann`s we use the formula,

Here, d is distance and t is time and v if we take it with direction then it is called velocity and if we take it without the direction then it is called speed.

Given and .

Substituting these values in above equation we get

As Ann walked towards south direction therefore, Ann`s velocity is 3 mi/h south and her speed is 3 mi/h .

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
