Compare the motion of two blue jays. Which blue jay was moving at a lower speed?
a blue jay that moved 180kilometers in 5hours a blue jay that moved 190kilometers 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 two objects moving for the same amount of time. The object that is moving slower will go a shorter distance in that time. It is moving at a lower speed.
Look at the distance each blue jay moved and the time it took to move that distance.
One blue jay moved 180 kilometers in 5 hours.
The other blue jay moved 190 kilometers in 5 hours.
Notice that each blue jay spent the same amount of time moving. The blue jay that moved 180 kilometers moved a shorter distance in that time. So, that blue jay must have moved at a lower speed.
