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]}

63 \cdot 60 = 270x
3780 = 270x\quad |:270
x=14[miles]

His average speed is 14 miles per hour.

Shalnov [3]

HI Brainiac


-5x-15 > 10+20x

-5x-20x > 10+15

-25x > 25

Divide both sides by -25

-25x/-25 > 25/-25

x < -1

Answer : B


I hope that's help:)
