The Curiosity Rover has recently landed on Mars and likes to send Twitter updates on its progress. If a tweet is posted 14 minutes after it was sent, how far is Curiosity from Earth?
Answer:
2.7 x 10¹¹ m
Explanation:
Given,
time (t) = 14 minutes * 60s/min = 840s
1 min = 60 s
15 min = 15 x 60 = 900 s
Distance (D) = Velocity (v) * t
v = Speed of light = 3 x 10⁸ m/s
D = 3E8 x 840
D = 2.52E11 m
