The doctor's average speed for the whole trip is 75 km per hour. His average velocity for the whole trip is zero.

The average speed of the doctor is 75 km per hour and his average velocity should be zero.

Given that,

  • The distance should be 75 km.
  • And, the time taken is 1.0 hours.
  • Here we assume that we have to determine the speed.

Based on the above information, the calculation is as follows:

We know that

[tex]Speed = \frac{Distance}{Time}\\\\= \frac{75}{1}[/tex]

= 75 km per hour

Therefore we can conclude that the average speed of the doctor is 75 km per hour and his average velocity should be zero.
