Question

How many km are equal to 1.55x10^4

Answer 1

Answer:

$15.5$ or  $x=1.55\times 10$ kilometers

Step-by-step explanation:

We want to find how many kilometers are equal to $1.55\times 10^4$ meters.

Recall that: $1000m =1km$

We can rewrite  $1.55\times 10^4$ as $15500$

Let $15500m=x\:km$

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

If more, then less divides:

$\implies x=\frac{15500}{1000} km$

$\implies x=15.5km$

Therefore  $1.55\times 10^4$ meters is equal to $15.5$ or  $x=1.55\times 10$ kilometers
