Answer 1

Answer:

time required = $1.87*10^{17}$ seconds.

Explanation:

Given that, speed = $3*10^{8}$ m/s

                  distance = $5.6*10^{25}$

                  time = ?

FORMULA :  $speed=\frac{distance}{time}$

      =>  $3*10^{8}$ = $\frac{5.6*10^{25}}{time}$

      =>  time = $1.87*10^{17}$ seconds.

Answer 2

Hi Buddy! Hope this helps you!

Answer:

The time that is taken by light to travel this distance is 1.87×10¹⁷ seconds.

Explanation:

Given:

Distance of a galaxy from the earth: 5.6×10²⁵ m.

Speed of light: 3×10⁸ m s⁻¹

The time that is taken by light to travel this distance: ?

We know that,

                           S=v/t

                           S/v=t

                           5.6×10²⁵/3×10⁸=t

                           1.87×10¹⁷=t
