The student recorded the time taken for a vehicle to travel 40 km over 10 days to calculate its average speed. They noted the distance and time for each day's journey, then calculated the total distance of 400 km and total time of 510 minutes. Using the formula of total distance divided by total time, the average speed was determined to be 0.784 km/min.

2. Objective: To find the average speed of a vehicle in 10 days.
What to Do: Record the speed of a particular vehicle for 10 days and using
the obtained information, find the average speed.
Formula for Speed: Distance

3. Observation
Distance from house to office: 40 km
Day Time (minutes)
1 45
2 55
3 46
4 52
5 46
6 60
7 57
8 49
9 51
10 49

4. Formula
Average speed = Total distance
Total time
= 40 + 40 + 40 + 40 + 40 + 40 + 40 + 40 + 40 + 40
45 + 55 + 46 + 52 + 46 + 60 + 57 + 49 + 51 + 49
= 400
510
= 40
51
= 0.7843137254901961 km/m-1
= 0.784 km/m-1

5. Result
From this, we come to the conclusion that the average speed of the
car in 10 days is 0.784 km/m-1.
