How many meters are there in 4 and a half kilometers?

Answer 1

Remember in 1 kilometre there are 1000 metres.

So in 4 kilometres there are 4 x 1000 = 4000 m

In half a kilometre (0.5) there are 1000/2 = 500 metres.

So in 4.5 kilometres there are 4000 + 500 = 4500 metres.

Answer 2

4500 meters equals 4.5 kilometers.
