So we're told that a runner run 700 meters in 20 seconds and we want to find the runners average speed throughout the run. So the formula for speed is speed is equal to d. Over t, where d is distance and t is time to speed, is equal to distance over time. So, let's plug in what we know. We know what we're trying to find the average speed, and we know the runners distance, that the runner runs is 100 meters and always make sure to include your units, and we know that the time it takes the runner to run this distance is 20 seconds. So once again include your units, so now we simply have 100 over 20, which is 5 point, and then we also have to keep our units, so we made sure to divide it by this so m over s or meters over second simply just denotes out. 2 meters over seconds, so you'll have 5 meter per second, and this is why it's important to include your units, like i said earlier, if you don't include your units over here, then all you would end up with is 5 and 5 is just incorrect and in Some sort of real test what weascenaria need to know the units so 5 meter per second, that's our final answer and that works out, because meters per second is an s. I units our final answer.
