The motorcyclist drove for 2 hours at a speed of 65 km / h and 3 hours at a speed of 75 km / h

The motorcyclist drove for 2 hours at a speed of 65 km / h and 3 hours at a speed of 75 km / h. Find the average speed of the motorcyclist along the way.

Let’s determine what distance the motorcyclist traveled in two hours, if his speed was 65 kilometers per hour.
2 × 65 = 130 kilometers.
Let’s determine what distance the motorcyclist traveled in three hours, moving at a speed of 75 kilometers per hour.
3 × 75 = 225 kilometers.
Let’s find out how many kilometers the motorcyclist traveled.
225 + 130 = 355 kilometers.
The time taken for the entire journey was:
3 + 2 = 5 hours.
Average rider speed:
355: 5 = 71 kilometers per hour.
Answer: 71 kilometers per hour.
