For this case, we have that by definition:


v = \frac {x} {t}

Where:

v: It's the average speed

x: It is distance traveled (movement in one direction)

t: It's time

We have to:


x = 200 \ miles\\v = 25 \ miles \ for \ hour

So:


t = \frac {x} {v}\\t = \frac {200} {25}\\t = 8 \ hours

Answer:


t = 8 \ hours

Option B
