In "Dead or Alive" the group determines that Barry needs to cover a certain distance to Savatar (it looked to be approximately 30 or 40 feet) in .21 seconds in order to save Iris.
They determine that this is not possible considering Barry's current speed. Yet when Barry decides to train Wally to save Iris, we see Wally's listed speed as 1,881 mph. Which was about equal to Barry's speed.
This speed equates to approximately .5225 miles per second which is about 2,758.8 feet per second. So in .21 seconds, Barry should already be able to travel 579 feet. This is much farther than the distance he needs to travel in order to save Iris.
