Light travels at 3 x 105 km/s (300,000 km or 186,000 miles). How long will it take to get to earth? (A distance of 1.5 x 108 km)

Vlad1618 [11]

Answer:

Option (4)

Explanation:

Here, Speed of light= $3\times10^5$ Km/sec

Distance= $1.5\times10^8$ Km

We know that,

$Speed=\frac{Distance}{Time}$

$\implies Time=\frac{Distance}{Speed}$

$Time=\frac{1.5\times10^8}{3\times 10^5}$

$=0.5 \times10^3$

=500 sec

=8 minutes 20 sec

Hence, the correct answer is option (4) i.e 8 minutes.
