The motorcyclist drove 90 km in the first two hours and moved at a speed of 50 km / h for the next three hours.

The motorcyclist drove 90 km in the first two hours and moved at a speed of 50 km / h for the next three hours. What is the average speed of a motorcyclist along the way?

Let’s find the distance covered by the motorcyclist in 3 hours of movement at a speed of 50 km / h:

S2 = 3 * 50 = 150 (km).

The length of the entire path of the motorcyclist was:

S = S1 + S2 = 90 + 150 = 240 (km).

The total travel time was:

t = t1 + t2 = 2 + 3 = 5 (h).

Let’s determine the average speed of a motorcyclist along the entire path:

V = S / t = 240/5 = 48 (km / h).

Answer: The average speed of a motorcyclist is 48 km / h.
