# How long does it take for light (in minutes) to reach Saturn from the Sun, at a distance of 1.532 × 109 km?

Dec 5, 2015

t = 1.418 hours

#### Explanation:

This can be Calculated from

D = c * t

where,

D is the distance to the Object
c is the Speed of light 300,000 km /sec
t is the time light takes to reach us

D is 1.532 x ${10}^{9}$ km
c is 300,000 km/ sec
t is to be found

1.532 x ${10}^{9}$ / 300,000 = t

t = 5106.66 seconds
OR

t = 1.418 hours
