Question

The speed of 150KM/hr is equivalent to how many miles per hour?

Answer 1

Hint: Kilometer per hour is the unit for measuring speed, in the similar manner miles per hour but miles is longer than kilometer
1 mile = 1.609 kilometer or 1km =0.6214 miles

Complete step by step answer:
Kilometer is the unit of length in the metric system, equal to one thousand meters. It is now the unit of measurement used for expressing distances between geographical places on land in most of the world. When the distance is calculated in kilometers then speed also is calculated as kilometers per hour. Generally, Kilometer is used in American standards.
Miles is the unit of length. Generally miles is used by United kingdom standards. Miles are larger units than Kilometers.

As per the conversion 1 mile = 1.609 kilometer or $1km = 0.6214miles$
Since, we are being asked to convert Kilometer per hour to miles per hour therefore no change in the units of time take place and only kilometer will be changed to miles.
150 Kilometer is changed to miles as per the relation between kilometer and miles.
Therefore, in miles per hour speed will be;
$ \Rightarrow 150 \times 0.6214$
$ \Rightarrow 93.21$ miles per hour

Note: Measurement of length has many other units such as meter, feet, inch, centimeter, millimeter, nautical miles. Each of the above mentioned units are related to each other with like $1$meter $=100$centimeter, $1$meter $=1000$millimeter, $1$meter $=39.37$ inches, and so on.
