Michelle Ann conducted an experiment on speed using her toy car. She listed all the data she gathered in the table below. Upon analyzing her data, she concluded that toy car C is the slowest among the four. Do you think her conclusion is correct?

• A.   Yes, because its speed is 20m/s.

• B.   Yes, because it has the greatest time recorded.

• C.   No, because all the toy car travelled the same distance.

• D.   No, because the slowest toy car is the one that took the least time.

Marlow was asked by her teacher how to solve the speed of an object. She said that to solve for the speed of an object, one must multiply the distance travelled by the recorded time of travel. Do you think her process is correct?

• A.   Yes, because multiplication is the way to solve for speed.

• B.   Yes, because she had all the needed data like distance and time.

• C.   No, because in solving for speed one must divide the distance travelled by the recorded time of travel.

• D. No, because in solving for speed one must add the recorded time and the distance travelled.
