[Maths Class Notes] on Mile Pdf for Exam

A mile is defined as the unit of length, which is exactly equal to 5280 feet, or 1760 yards, and standardized as exactly 1609.344 meters by the International agreement in 1959. It is the largest unit that is commonly used to measure the distance between places that are far from each other.

While most of the countries replaced mile with kilometres when turning to the International System of Units, the international miles continues to be used in some countries such as the United Kingdom, United States, Liberia and a number of countries with less than 1 million inhabitants, most of which are US and UK territories or have a close tie-up with the US or UK.

Mile Symbol

The mile symbol ‘m’ was commonly used before the widespread adoption of the metric system, but after the adoption of the metric system, ‘mi’ became the preferred mile symbol to avoid confusion between miles and meters.

What is One Mile?

There are two types of miles namely nautical miles and statute miles.

1 Mile (Statute)= 5280 Feet = 1760 Yards = 63,360 inches

1 Mile (Nautical) = 6080.2 Feet = 2025.371 yards = 72913.3

How Much is a Mile?

A mile is exactly 1.609344 kilometres or 1609.34 meters. It usually takes 15-20 minutes to cover 1 mile by walking at a moderate pace.

Feets Per Mile

The Romans divided their miles into 5000 feet. In the US and UK, the mile unit is commonly referred to as the statute mile which is equivalent to 8 furlongs or 5280 feet. The statute mile was introduced long back in England, in 1953 due to the importance of furlong. 

How to Remember Feet Per Mile

A mnemonic “ Five Tomatoes” is a precise way to remember that there are 5280 feet in a mile as it sounds like “ five two eight oh”.

How Nautical Miles are Defined in Terms of Feet?

A nautical mile (abbreviated as m, nm or nmi) is a unit of length used in space navigation and air marine.

In the United States, the nautical mile was defined as 6080.2 feet long back in the 19 century whereas, in the United Kingdom, the nautical mile was defined as 6080 feet and was approximately one minute of latitude in the latitude of the south of the UK. In other countries of the UK, the nautical mile is defined differently, but now the nautical mile is defined internationally as 1852 metres or 6076.1154 feet.

Facts to Remember

• 1 nautical mile = 1.150779448 miles

• 1 nautical mile = 6076.12 feet

• I statute mile = 5280 feet

Mile Unit Conversion Examples With Solution

1. Convert 15 Miles into Statute Feet.

Solution:

As we know, 

1 mi = 5280 statue ft

Accordingly,

To convert statute 15 mi into ft, we will multiply 15 by 5280.

= 15 x 5280 

= 79200 ft

Hence, 15 statute miles is equivalent to 79200 feet.

2. Convert 15 Miles into Nautical Feet.

Solution:

As we know, 

1 mi = 6076.12 statue ft

Accordingly,

To convert 15 nautical mi into ft, we will multiply 15 by 6076.12.

= 15 x 6076.12

= 91,141.8 ft

Hence, 15 nautical miles is equivalent to 91,141.8 feet.

3. Convert 15 Miles into Metres.

Solution:

As we know, 

1 mi = 1609.344 m

Accordingly,

To convert 15 mi into m, we will multiply 15 by 1609.344.

= 15 x 1609.344

= 24140.16 m

Hence, 15 miles is equivalent to 24140.16 metres.

4. Convert 15 miles into Kilometres.

Solution:

As we know, 

1 mi = 1.60934 km

Accordingly,

To convert 15 mi into m, we will multiply 15 by 1.60934.

= 15 x 1.60934

= 24.1402 m

Hence, 15 miles is equivalent to 24.1402 kilometres.
