Use of Decimal in Measuring the Distance

We will learn the use of decimal in measuring the distance.

As we already know that,

1000 metres = 1 kilometre or 1000 m = 1 km

So, 1 m is one thousandths of a km.

or, 1 m = \(\frac{1}{1000}\) km  = 0.001 km

Similarly, 250 m = 0.250 km or 0.25 km   (250 metres is twenty five thousandths of a kilometre)

617 m = 0.617 km  (617 metres is sixty hundred seventeen thousandths of a kilometre)

Kilometres and metres can be expressed together as decimals.

For example,

14 km 252 m = 14.252 km

77 km 17 m = 77.017 km

93 km 103 m = 93.103 km

116 km 42 m = 116.042 km

207 km 119 m = 207.119 km

320 km 21 m = 320.021 km
