Question

How many km are equal to 1.55x10^4

Answer 1

`15.5` or
`x=1.55* 10` kilometers

Explanation:

We want to find how many kilometers are equal to
`1.55* 10^4` meters.

Recall that:
`1000m =1km`

We can rewrite
`1.55* 10^4` as
`15500`

Let
`15500m=x\:km`

Using proportion,
`15500` should be more than 1km.

If more, then less divides:

`\implies x=(15500)/(1000) km`

`\implies x=15.5km`

Therefore
`1.55* 10^4` meters is equal to
`15.5` or
`x=1.55* 10` kilometers
