Cleveland's pool is 50 meters long, so 8 lengths is what Sam needs to swim for the 400-meter competition coming up.He is now at home (coronavirus!) but coach says he still needs to practice.The problem is that his parents have a very old pool, and it is only 50 yards long!If he swims 8 lengths of this pool (400 yards),abouthow manyyardsdoes he have left to swim?
