Question

How Many hours are there in 4380 Minutes?

Answer 1

Hint: By using the definitions try to categorize the given units into any type possible. Try to convert one unit into another unit by using the inter relations you know. The changed value in the new unit system is the required result in the question on conversion.

Complete step-by-step answer:
Measurement: Measurement is assignment of a number to a characteristic of an object or events. The scope and application of measurements are dependent on the context and disciple. The measurements can be compared with other objects or events. Measurements do not apply to nominal properties of an object or an event.
Unit of measurement: A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity. Any other quantity of that kind can be expressed as a multiple of the unit measurement unit is the point used in the process of determining how large or small a physical quantity is as compared to a basic reference quantity of the same kind. This basic reference is called Si (which is an abbreviation for international system of units). There are seven Si base units, which are length (meter), time(seconds), amount(mole), electric current (A), temperature (Kelvin), luminous intensity(candela), mass (kilograms).
Given, measurements in the question can be written in form 4380 minutes.
This measurement comes under time, type of units as minutes. The intersection of time can be written in the form of:
1 hour = 60 minutes.
By dividing with 60 on both sides, we can write it in form
 $ 1\,minute=\dfrac{1}{60}hour...........(i) $
Let us assume a measurement in an hour given by variable k.
Let this k be the value of 4380 minutes in hours.
So, mathematically we can write it in the form of:
k hours= 4380 minutes.
By substituting equation (i), we can write it as:
\[k\text{ }hours=\text{ }4380\text{ }\times \text{1}\,minutes\]
By taking value of 1 minute, we can write it as:
 $ k\,hours=4380\times \dfrac{1}{60}hours $
By simplifying, we can write it in the form of:
 $ k\,hours=\dfrac{4380}{60}hours=73\,hours $
k=73. So, the value of 4380 minutes is 73 hours.

Note: Be careful while conversion, as the value of hours is converted into minutes by dividing 60 not multiplying. Don’t confuse between the steps. So, we must remember hours units are greater than minutes, minutes units are greater than seconds. This relation is very important to solve: hours > minutes > seconds.
