Question

light travels a speed of 1.86 x 10^5. it takes light from the sun about 4.8 x 10^3 seconds to Saturn. find the approximate distance from Sun to Saturn. Enter you’re answer in scientific notation.

Answer 1

The distance is the product between the speed and the time elapsed, so we have

`1.86 * 10^5\cdot 4.8 * 10^3=(1.86\cdot 4.8)* 10^(5+3)=8.928* 10^8`
