Question

a train runs at 72 km per hour what is its speed in metre per minute​

Answer 1

As per the data given in the question,

We have to convert the speed from Km per hour to the metre per minute.

As we know that,

$1 \:Km=1000\:m$

And, $1\:Hr = 60\:minutes$

So, for converting km/Hr into m/min. we need to do the following operations,

$\frac{Km}{Hr} \\= \frac{1000}{60} \\= \frac{50}{3}$

So, multiplying the speed 72 Km per hour by $\frac{50}{3}$ for converting it into metre per minutes,

We will get it as,

$72 \times \frac{50}{3}\\=> 1200 \:m/minutes$

Answer 2

Speed Conversion

Converting km/h to m/s means that we are converting the units of a given speed from kilometer per hour to meter per minute.

To convert kilometre/hour [km/h] to meter/minute [m/min] for an approximate result, we have to multiply the speed value by 16.667 to get a value in m/min.

We know that,

$\boxed{\textrm{1 km/h = 16.66667 m/min}}$

Therefore 72 km/h in m/min will be:

$\implies \rm{72 \; km/h = 72 \times 16.66667 \; m/min}$

$\implies \boxed{\textbf{72 km/h = 1200 m/min}}$

Hence, the speed in metre per minute is 1200 (approximately).
