Answer:

2.04\times 10^{6}\ years

Step-by-step explanation:

Given:

Distance from Sun to Andromeda galaxy (D) = 1.2\times10^{19}\ miles

Speed of light (s) = 5.88\times 10^{12}\ miles\ per\ year

Now, we need to find the time required for light to reach the galaxy from the Sun.

Let the time be 't' years.

Now, we know that, distance traveled by the light will be equal to the product of its speed and time taken by it. Therefore, framing in equation form, we get:

Distance=Speed\times Time\\\\D=s\times t

Now, plug in the given values and solve for time 't', This gives,

1.2\times 10^{19}=5.88\times 10^{12}\times t\\\\t=\frac{1.2\times 10^{19}}{5.88\times 10^{12}}\ years\\\\t=2.04\times 10^{6}\ years

Therefore, light will reach the Andromeda galaxy in 2.04\times 10^{6}\ years.
