Question

From the list of world record track events in the table, calculate the average speeds for each race. Assume the length of each event is known to the nearest 0.1 m. Calculate only the last one, for 10,000 m.

Answer 1

Answer:

0.095 m/s

Explanation:

The average speed can be calculated as

Avg speed = distance/time

For the last one, we get that distance is 10000 m and the time 29 hours, 17 min, and 45 seconds.

So, first, we need to convert 29:17.45 to seconds as follows

29 hours x 3600 s/ 1 hour = 104400 s

17 min x 60 s / 1 min = 1020 s

45 s = 45 s

Total time = 104400 s + 1020 s + 45 s

Total time = 105,465 s

Then, the average speed is equal to

Avg speed = 10,000 m/105,465 s

Avg speed = 0.095 m/s

Therefore, the answer is 0.095 m/s
