Question

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

Answer 1

`196\ miles`

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=(y)/(x)`

In this problem we have

`x=3(1)/(2)\ hours=3.5\ hours`

`s=56\ mph`

substitute and solve for y

`56=(y)/(3.5)`

`y=56*3.5=196\ miles`
