Question

A bus drives 3 1/2 hours at an average speed of 56mph how far does the bus drive?

Answer 1

Answer:

$196\ miles$

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

$s=\frac{y}{x}$

In this problem we have

$x=3\frac{1}{2}\ hours=3.5\ hours$

$s=56\ mph$

substitute and solve for y

$56=\frac{y}{3.5}$

$y=56*3.5=196\ miles$
