Owen runs a third of a trip at 3 meters per second, and then he runs at 5 meters per second for the rest of the trip. What is the average speed he runs for the entire trip? Express your answer as a mixed number.

Step-by-step explanation:

Note: When a body is travelling at uniform acceleration, the average velocity is given as  

Given

initial velocity u= 3 m/s

final velocity v= 5 m/s

To express this in mixed number we have
