Question

Calculate the average times it took the car to travel 0. 25 and 0. 50 meters. Record the averages, to two decimal places, in Table C of your Student Guide. What is the average time it took the car to travel 0. 25 meters? seconds What is the average time it took the car to travel 0. 50 meters? seconds.

Answer 1

The average speed of the given car is 2.22 s and 3.13 s for 0.25 m and 0.50 m distance respectively.

How to calculate the Average speed?

The average speed can be calculated by adding the speed of each trial divided by the number of trials,

For 0.25 m the average speed will be:

$S_{avg} = \dfrac{2.24 + 2.21 + 2.23}{ 3}\\\\S_{avg} = 2.22$

For the 0.50 m, the average speed will:

$S_{avg} = \dfrac {3.16 + 3.08 + 3.15} {3 }\\\\S_{avg} = 3.13\rm \ s$

Therefore, the average speed of the given car is 2.22 s and 3.13 s for 0.25 m and 0.50 m distance respectively.
