<h3>Speed of light:</h3>

$3.05 \times 10 ^{8} m/s$

<h3 /><h3>Seconds in a year:</h3>

$3.15 \times 10 ^{7}$

$\rule{300pt}{3pt}$

Multiply the speed of light with seconds in a year

*Note:- We will not change the values because speed of light is in m/s and the time is also given in seconds.

$\rule{300pt}{3pt}$

$3.08 \times 10 ^{8} \times 3.15 \times 10 ^{7}$

$(3.05 \times 3.15) \times (10 ^{8} \times 10 ^{7} )$

$9.4675 \times 10 ^{15}$

$\tt9.46 \: Trillion \: Kilometers$
