Question

The speed of a train is expressed in m/h. True or false

Answer 1

Answer:

False

Explanation:

The speed of train is measured either in km/h or m/s.

Answer 2

False.

Speed is defined as the rate of change of distance with time. Thus, mathematically giving us,

s = $\frac{distance}{time}$

as the SI units of distance and time are meters (m) and seconds (s) respectively, the SI unit of Speed is meter/second or $\frac{m}{s}$.

But this unit is used only in scientific and academic circles. Most people know the unit of speed in kilometres per hour or $\frac{km}{hr}$.

Note: The American measuring system is different from the rest of the world. The measure speed in miles/hour. Therefore, if you are studying in a school certified from an american board. The 'm' in the question could stand for miles which makes the statement true.
