In the table shown, how do you find the total distance and total time to calculate average speed?

• Add up the times and add up the distances

• look at the top row

• look at the last row

• Add up the distance and time in the last row

To find average speed, you must find the total distance and total time. Given the table above, how do you find the total distance and total time in order to calculate average speed?

• You look at the distance and time in the 3rd trial

• You look at the distance and time in the 2nd trial

• You look at distance and time in the 1st trial

• You add up all 3 times recorded for the total time and all 3 distances recorded for the total distance.

Using the table shown above, what is the average speed of the wind-up toy.

• 6.2 m/sec

• 6 m/sec

• 5 m/sec

• 6.5 m/sec
