Question

The star Betelgeuse, in the constellation of Orion, is approximately $3.36\times {10}^{15}$ miles from Earth. This is approximately $1.24\times {10}^6$ times as far as Pluto's minimum distance from Earth. What is Pluto's approximate minimum distance from Earth? Write your answer in scientific notation.

Answer 1

Let Pluto's approximate minimum distance from Earth be $x$ miles
Thus, $1.24\times {10}^6\times x=3.36\times {10}^{15}$
$=>x=\frac{3.36\times {10}^{15}}{1.24\times {10}^6}$
$=>x=2.7\times {10}^9$
