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

The formula for velocity is V=D/T, where V is Velocity, D is distance and T is time. You have the distance, which is 250 meters (this is how many meters she ran for). You have the time, which is 28 seconds (this is how long she ran for). You simply plug those values into the velocity formula and solve for V (velocity).

I can explain it again if you do not understand it. Is the formula confusing?
