Compare the motion of two blue jays. Which blue jay was moving at a higher speed?
a blue jay that moved 330kilometers in 10hours a blue jay that moved 315kilometers 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 kilometer.
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 blue jay moved and the time it took to move that distance.
One blue jay moved 330 kilometers in 10 hours.
The other blue jay moved 315 kilometers in 10 hours.
Notice that each blue jay spent the same amount of time moving. The blue jay that moved 330 kilometers moved a farther distance in that time. So, that blue jay must have moved at a higher speed.
