Answer 2

Answer : The correct option is, (d)

Step-by-step explanation:

We are given 32 kilometers and we need to convert it into meters, so for that the conversion factor used is:

1 km = 1000 m

So, 32 kilometers will be equal to:

32 km =
`32* 1000m=32000m=3.2* 10^(4)m`

Hence in 32 km there are
`3.2* 10^4m`

So, the correct option is option d.
