Answer:
The runner attain to 18 miles per hour speed.
Step-by-step explanation:
First we calculate the velocity in meters per second:
![v=e/t](https://tex.z-dn.net/?f=v%3De%2Ft)
Where v is velocity, e is distance traveled, and t time taken to travel the distance e.
![v=400m/50sec=8m/s](https://tex.z-dn.net/?f=v%3D400m%2F50sec%3D8m%2Fs)
So, the speed is 8m/s and now we need to convet to miles per hour.
![\frac{8m/s}{1609m}*\frac{1mile\int\limits^a_b {x} \, dx }{1hour}*3600s=17,89](https://tex.z-dn.net/?f=%5Cfrac%7B8m%2Fs%7D%7B1609m%7D%2A%5Cfrac%7B1mile%5Cint%5Climits%5Ea_b%20%7Bx%7D%20%5C%2C%20dx%20%7D%7B1hour%7D%2A3600s%3D17%2C89)
Rounded: 18 miles per hour
