The motorcyclist covered 16 km in the first 20 minutes, and 34 km in the next 16 minutes. what is the average speed of a motorcyclist along the way?
Initial data: t1 (time in the first section) = 20 min (1/3 h); S1 (length of the first section) = 16 km; t2 (time in the second section) = 16 min (4/15 h); S2 (length of the second section) = 34 km.
The average speed of a motorcyclist along the entire path can be calculated by the formula: Vav. = (S1 + S2) / (t1 + t2).
Calculation: Vav. = (16 + 34) / (1/3 + 4/15) = 50/9/15 = 50 * 15/9 = 83.3 km / h (23.14 m / s).
Answer: The average speed of a motorcyclist all the way is 83.3 km / h or 23.14 m / s.
