Answer:
v = 15.72 mi/hr
Step-by-step 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=(d)/(t)\\\\v=\frac{1\ \text{mile}}{3.81\ \text{}min}\\\\v=0.262\ mi/min](https://img.qammunity.org/2021/formulas/physics/high-school/7q79glpmz28bfeptq68mx6vraovh7387w4.png)
We know that,
1 hour = 60 minute
So, average speed is :
![v=\frac{0.262\ \text{mile}}{\text{min}}\\\\v=\frac{0.262\ \text{miles}}{(1)/(60)h}\\\\v=15.72\ mi/hr](https://img.qammunity.org/2021/formulas/physics/high-school/p956fvfl0qnknq6dt58m3qlogpr5dwz0em.png)
So, the average velocity is 15.72 mi/h.
