Question

The distance between the earth and the sun is 90.0 million miles. Calculate this distance in meters up to three significant digits. (1 mile = 1609.344 meters)

Answer 1

Multiply 90 by 1,609.344: 144,840.96 meters :)

Answer 2

The distance is
`1.45* 10^(11)` meters.

Step-by-step explanation:

Distance of the earth from the sun = 90.0 million miles

=
`90* 10^6 miles=9* 10^7 miles`

1 mile = 1609.344 meters

`9* 10^7 miles=9* 1067* 1609.344 meters`

`=1.448* 10^(11) m\approx 1.45* 10^(11) m`
