The total **displacement **of the motorcyclist is 179.58 km and its the average velocity is 63.38km/h.

**Motorcyclist **drive to north for 35 minutes at 85km/h. After that, he drives 130km in 2 hours towards the north.

We know,

Velocity = **displacement**/time

So,

We can write,

Displacement = velocity × time

Displacement = 85 × 35/60

Displacement = 49.58 km

After stopping for 15 minutes.

He moves again till a distance of 130 km. As the direction is not changing,

So the total displacement is,

Total **Displacement **= 179.58 km.

We know,

**Average velocity **= total displacement/total time

**Total time** = time for which he moved and time for which he stopped.

Total time = (0.58 + 0.25 + 2)hours

Total time = 2.88 hours.

Now, putting values,

Average velocity = 179.58/2.88

Average velocity = 63.38km/h

So, the **average velocity **of the motorcyclist is 63.38km/h.
