A. When we compare how quickly time and distance change, we can call that ________ .
There is a formula we can use to calculate speed:
Speed = ________________ divided by _____________
For example, the drinking fountain is about twenty meters from the classroom. It takes you about 5 seconds to walk
there from the classroom. So your speed:
Speed = distance / time
Speed = 20m / 5 s
Speed = 4 m/s (This would be said as four meters per second.)
Of course you don’t walk the same speed the entire time. We actually calculated your _______________
