Answer:
[tex]196\ miles[/tex]
Step-by-step explanation:
we know that
The speed is equal to divide the distance by the time
Let
y-----> the distance in miles
x-----> the time in hours
s----> the speed in mph
so
[tex]s=\frac{y}{x}[/tex]
In this problem we have
[tex]x=3\frac{1}{2}\ hours=3.5\ hours[/tex]
[tex]s=56\ mph[/tex]
substitute and solve for y
[tex]56=\frac{y}{3.5}[/tex]
[tex]y=56*3.5=196\ miles[/tex]
