Question

How long does it take a car to travel 200 miles at a constant speed of 25 miles per hour? 4 h 8 h 10 h 12 h

Answer 1

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

Answer 2

25 mph x 8h = 200 mph
So the answer is 8 h
