Question

the planet. Assume the speed of light is 300,000 km per second.
7.5 A planet is 300 million km away from a star. How much time will light take to travel from the star to​

Answer 1

16.667 min

Explanation:

300,000km/sec

time = distance/time

time= 300000000/300000= 1000sec Or 16.667 min

Answer 2

Answer:

50 minutes

Explanation:

$time \: taken \: by \: light \: to \: travel \: 300000 \: km = 1 \: second \\ time \: taken \: by \: light \: to \: travel \: 1 \: km = \frac{1}{300000}seconds \\ time \: taken \: by \: light \: to \: travel \: 300000000 \: km = \frac{300000000}{300000} \\ \\ = 1000 \: seconds \\ 1 \: second = \frac{1}{60} minutes \\ 3000 \: seconds = \frac{1000}{60} \: minutes \\ = 16.7 \: minutes$
