Question

Tom travels between the two mile markers shown and then finds his average speed in miles per hour. Select the three equations that represent this situation.

Answer 1

Answer:

1.5 hours is the correct answer !

Step-by-step explanation:

Answer 2

Speed is the rate of distance over time.

The equations are:

• $\mathbf{Speed = \frac{195\ miles}{3\ hours}}$

• $\mathbf{3\ hours \times Speed = 195\ miles}$

• $\mathbf{3\ hours = \frac{195\ miles}{Speed}}$

The given parameters are:

$\mathbf{(t_1,d_1) = (1:30pm,35miles)}$

$\mathbf{(t_2,d_2) = (4:30pm,230miles)}$

So, the time difference is:

$\mathbf{t=4:30pm - 1:30pm}$

$\mathbf{t=3\ hours}$

The distance traveled is:

$\mathbf{d = 230miles - 35miles}$

$\mathbf{d = 195miles}$

Speed is calculated as:

$\mathbf{Speed = \frac{Distance}{Time}}$

So, we have:

$\mathbf{Speed = \frac{195\ miles}{3\ hours}}$

Multiply both sides by 3 hours

$\mathbf{3\ hours \times Speed = 195\ miles}$

Divide both sides by Speed

$\mathbf{3\ hours = \frac{195\ miles}{Speed}}$

Hence, the equations are:

$\mathbf{Speed = \frac{195\ miles}{3\ hours}}$

$\mathbf{3\ hours \times Speed = 195\ miles}$

$\mathbf{3\ hours = \frac{195\ miles}{Speed}}$
