Compare the motion of three geese. Which goose was moving at the highest speed?
A: a goose that moved 675miles north in 10hours
B: a goose that moved 575miles west in 10hours
C: a goose that moved 765miles north in 10hours
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 10 hours. The goose that moved 765 miles moved the farthest distance in that time. So, that goose must have moved at the highest speed.
