Question

Maglev, a vehicle that glides above a magnetic field without touching a track, make a 624-mile trip in 4 hours. What is the speed of the vehicle?

Answer 1

Answer:

The speed of the vehicle is 156 miles per hour.

Explanation:

Let suppose that the Maglev, that is, a vehicle who works on the principle of superconductive magnetic levitation, moves at constant speed. Hence, the speed of the vehicle ($v$), in miles per hour, is defined by this kinematic model:

$v = \frac{s}{t}$ (1)

Where:

$s$ - Travelled distance, in miles.

$t$ - Time, in hours.

If we know that $s = 624\,mi$ and $t = 4\,h$, then the speed of the vehicle is:

$v = \frac{624\,mi}{4\,h}$

$v = 156\,\frac{mi}{h}$

The speed of the vehicle is 156 miles per hour.
