Answer:
Elena's initial velocity is 0 because she is not moving. Her final velocity is 250 meters because that is the distance she finished at. The amount of time she ran for is 28 seconds.
Step-by-step explanation:
Hello send d D. Velocity is expressed in terms of distance per time, or V= D/T. We know that Elena's initial velocity is 0 because she is not moving. Her final velocity is 250 meters because that is the distance she finished at. The amount of time she ran for is 28 seconds. We can substitute the values we have for distance and time into the equation and solve for velocity.
V=D/T
V= 250 meters/28 seconds
V= 8.93 meters/second
