Homi · Accepted Answer

We need to convert a length from centimetres to kilometres using standard unit conversions.

Step 1 — Convert centimetres to metres

First, let us convert the given length from centimetres to metres. We know that 1 metre (m) is equal to 100 centimetres (cm). So, to convert cm to m, we divide by 100.

$60,00,000 \text{ cm} = \frac{60,00,000}{100} \text{ m}$

$= 60,000 \text{ m}$

$\boxed{60,000 \text{ metres}}$

Step 2 — Convert metres to kilometres

Next, let us convert the length from metres to kilometres. We know that 1 kilometre (km) is equal to 1000 metres (m). So, to convert m to km, we divide by 1000.

$60,000 \text{ m} = \frac{60,000}{1000} \text{ km}$

$= 60 \text{ km}$

$\boxed{60 \text{ kilometres}}$
