There are approximately 1609 meters per mile. If the sun is 93 million miles away, how far is the sun in kilometers to two significant figures.

d=149637 x 10³ km

Explanation:

Given that

1 mile = 1609 meters

The distance of the sun, d = 93 million

We know that

1 million = 10⁶

Therefore

93 million = 93 x 10⁶

d = 93 x 10⁶ x 1609 meters

d=149637 x 10⁶ meters

We know that 1000 m = 10 km

That is why we can say that

d=149637 x 10³ km

Therefore the distance d will be 149637 x 10³ km.
