# The motorcyclist covered 16 km in the first 20 minutes, and 34 km in the next 16 minutes.

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.
