Question

Ram has to attend a birthday party of his best friend - Sam. He asks his mum where Sam's home is, and she says he lives 2 km away from their home. But, how far is 2 km exactly? Can you tell how many millimetres make a kilometre?

• A.
• B.
• C.
• D.

Answer 1

The correct option is D

We know that, 1 m = 1000 mm and 1 km = 1000 metre.
Therefore, 1 km = (1000 $\times$ 1000) mm = ${10}^6$ mm.
