Compare the motion of two geese. Which goose was moving at a higher speed?
a goose that moved 640miles in 10hours a goose that moved 290miles in 10hours
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 mile.
Time tells you how long the object has spent moving. One unit used to measure time is the hour.
Think about two objects moving for the same amount of time. The object that is moving faster will go a farther distance in that time. It is moving at a higher speed.
Look at the distance each goose moved and the time it took to move that distance.
One goose moved 640 miles in 10 hours.
The other goose moved 290 miles in 10 hours.
Notice that each goose spent the same amount of time moving. The goose that moved 640 miles moved a farther distance in that time. So, that goose must have moved at a higher speed.
