Question

2.) The speed of light in a vacuum is c = 300,000 km / s. The light of Sol takes 8 minutes and 19 seconds to reach Earth. Calculate the distance between the Sun and Earth

Answer 1

Answer:

149,700,000 km

Explanation:

First, convert the time to seconds.

8 min 19 sec = (8 min) (60 sec/min) + 19 sec = 499 sec

Distance = rate × time

d = (300,000 km/s) × (499 s)

d = 149,700,000 km

Answer 2

Answer:

149,700,000 km   (= 1.50 x 10⁸ km)

Explanation:

Given,

Speed of light, c = 300,000 km/s

Time Taken = 8 min 19 s = 499 seconds

Recall, Distance = Speed x Time

= 300,000 km/s   x 499 s

= 149,700,000 km

= 1.50 x 10⁸ km
