Question

In his famous race, a hare runs for a while, takes a nap, and then resumes running until he reaches the finish line. His total displacement from start to finish is 5.0 m east and 12 m north. The hare's total race time, including the time of napping, is 28 minutes. What is the hare's average speed in meters per minute?

Answer 1

Answer 2

Answer:

The average speed is 0.46 m/m.

Explanation:

Given that,

His total displacement from start to finish is 5.0 m east and 12 m north.

Time = 28 minute

We need to calculate the total distance

Using Pythagorean theorem

$D=\sqrt{(5.0)^2+(12)^2}$

Average speed :

Average speed is equal to the total distance divided total time.

We need to calculate the average speed

Using formula of average speed

$v=\dfrac{D}{t}$

Put the value into the formula

$v =\dfrac{\sqrt{(5.0)^2+(12)^2}}{28}$

$v=0.46\ m/m$

Hence, The average speed is 0.46 m/m.
