Compare the motion of three geese. Which goose was moving at the highest speed?
a goose that moved 280kilometers west in 5hours a goose that moved 350kilometers east in 5hours a goose that moved 375kilometers north in 5hours
An object's speed tells you how fast the object is moving. Speed depends on both distance and time.
Distance tells you how far the object has moved. One unit used to measure distance is the kilometer.
Time tells you how long the object has spent moving. One unit used to measure time is the hour.
Think about objects moving for the same amount of time. The object that is moving the fastest will go the farthest distance in that time. It is moving at the highest speed.
Look at the distance each goose moved and the time it took to move that distance. The direction each goose moved does not affect its speed.
Notice that each goose moved for 5 hours. The goose that moved 375 kilometers moved the farthest distance in that time. So, that goose must have moved at the highest speed.
