270 minutes = 4,5 hours = 4 hours and 30 minutes
60 minutes = 1 hour
63 miles per 270 minutes
x miles per 1 hour = 60 minutes
![\dfrac{63[miles]}{x[miles]} = \dfrac{270[minutes]}{60[minutes]}](https://tex.z-dn.net/?f=%5Cdfrac%7B63%5Bmiles%5D%7D%7Bx%5Bmiles%5D%7D%20%3D%20%5Cdfrac%7B270%5Bminutes%5D%7D%7B60%5Bminutes%5D%7D)


![x=14[miles]](https://tex.z-dn.net/?f=x%3D14%5Bmiles%5D)
His average speed is 14 miles per hour.
