Milwaukee is 121 mi (air miles) due west of grand rapids. maria drives 255 mi in 4.75 h from grand rapids to milwaukee around lake michigan. find
a. her average driving speed
b. her average travel velocity.

Average speed = (distance covered) / (time to cover the distance) =

                             (255mi) / (4.75 hr) = 53.68 miles per hour

Average velocity = (displacement) / (time)

       ("Displacement" is the distance and direction from the starting point
         to the end point, regardless of the route taken.)

                           = (121 miles west) / (4.75 hours) = 25.47 miles per hour west

The modern-day generator works on the principle of electromagnetic induction discovered by michael faraday in 1831-32. faraday discovered that the above flow of electric charges could be induced by moving an electrical conductor, such as a wire that contains electric charges, in a magnetic field.
