Question

Steve Cram of Great Britain ran a mile in 3.81 min. During this amazing run, what was Steve's average velocity in mi/hr

Answer 1

Answer:

v = 15.72 mi/hr

Explanation:

It is given that,

Steve Cram of Great Britain ran a mile in 3.81 min

We need to find Steve's average velocity in mi/hr.

Speed,

$v=\dfrac{d}{t}\\\\v=\dfrac{1\ \text{mile}}{3.81\ \text{}min}\\\\v=0.262\ mi/min$

We know that,

1 hour = 60 minute

So, average speed is :

$v=\dfrac{0.262\ \text{mile}}{\text{min}}\\\\v=\dfrac{0.262\ \text{miles}}{\dfrac{1}{60}h}\\\\v=15.72\ mi/hr$

So, the average velocity is 15.72 mi/h.
