we have
1) It took Azul [tex]1.75[/tex] hours bike the blue mountain trail
2) Azul averaged [tex]12.5[/tex] miles per hour
we know that
The speed is equal to
[tex]Speed=\frac{distance}{time}[/tex]
we have
[tex]speed=12.5\frac{miles}{hour}[/tex]
[tex]time=1.75\ hours[/tex]
Find the distance
[tex]distance=speed*time[/tex]
substitute the values
[tex]distance=12.5\frac{miles}{hour}*1.75\ hours=21.875\ miles[/tex]
therefore
the answer is
[tex]21.875\ miles[/tex]
