Calculate the average speed of a biathlete who covered 20 km in 55 minutes.
| January 14, 2021 | education
The average speed of movement of a biathlete is calculated by the formula:
Vav. = S / t, where S is the path covered by the biathlete (S = 20 km = 20,000 m), t is the time of movement of the biathlete (t = 55 min = 55 * 60 s = 3300 s).
Let’s calculate the average speed of a biathlete:
Vav. = S / t = 20,000 / 3300 = 6.06 m / s (21.81 km / h).
Answer: The average speed of a biathlete is 6.06 m / s or 21.81 km / h.
