A young Witch flew her broom 48 miles form her home to a witch festival. Flying with the wind, the trip took 3 hours. Her flight

vekshin1

Using the relation between velocity, distance and time, it is found that:

The speed of the wind is of 2 mph.

The speed of the broom is of 14 mph.

<h3>What is the relation between velocity, distance and time?</h3>

Velocity is <u>distance divided by time</u>, hence:

$v = \frac{d}{t}$

Flying with the wind, in which $v = v_b + v_w$ the 48-mile trip took 3 hours, hence:

$v = \frac{d}{t}$

$v_b + v_w = \frac{48}{3}$

$v_b + v_w = 16$

Her flight home against the wind took 4 fours, hence:

$v = \frac{d}{t}$

$v_b - v_w = \frac{48}{4}$

$v_b - v_w = 12$

Adding the two equations:

$2v_b = 28$

$v_b = 14$

$v_b + v_w = 16 \rightarrow v_w = 2$

Hence:

The speed of the wind is of 2 mph.

The speed of the broom is of 14 mph.
