Compare the motion of three cars. Which car was moving at the lowest speed?
a car that moved 210miles west in 5hours a car that moved 160miles north in 5hours a car that moved 225miles south 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 mile.
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 slowest will go the shortest distance in that time. It is moving at the lowest speed.
Look at the distance each car moved and the time it took to move that distance. The direction each car moved does not affect its speed.
Notice that each car moved for 5 hours. The car that moved 160 miles moved the shortest distance in that time. So, that car must have moved at the lowest speed.
