Question

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.

Answer 1

The answer in mixed number is
`=4(0)/(2)`

Explanation:

Note: When a body is travelling at uniform acceleration, the average velocity is given as
`Average -velocity= (v+u)/(2)\\\\`

Given

initial velocity u= 3 m/s

final velocity v= 5 m/s

`Average -velocity= (5+3)/(2)\\\\`

`Average-velocity= (8)/(2)`

To express this in mixed number we have
`=4(0)/(2)`
