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]
