Question

A doctor travels to the east from city A to city B 75 km in 0.5 hour .What is the doctor's average velocity?

Answer 1

Answer:

Avg Velocity is 150 km/hr

Explanation:

Avg Velocity = Total displacement / Total time taken

                     = 75 km / 0.5 hr

                     = 150 km/hr

Answer 2

Given - Displacement - 75 km

Time - 0.5 hour

Find - Average velocity

Solution - To calculate average velocity, the formula used is displacement/time.

Keeping the given values of displacement and time in equation to find average velocity.

Average velocity = 75/0.5

Average velocity = 150 kilometre/hour

Hence, the average velocity doctor is 150 kilometre/hour.

Average velocity can be defined as the change in position or in other words displacement per unit time.
