Question

Messages from the Perseverance Rover on Mars reach Earth in 11 min. The speed of light is 3.00 x 108 m/s. Using this information, how far is Mars from Earth?

Answer 1

Answer:

$d=1.98\times 10^{11}\ m$

Explanation:

Messages from the Perseverance Rover on Mars reach Earth in 11 min i.e. time is 660 s

The speed of light is $3\times 10^8\ m/s$

We need to find the distance between Mars and Earth. Let the distance be d.

We know that,

Distance = speed × time

So,

$d=660\times 3\times 10^8\\\\d=1.98\times 10^{11}\ m$

So, Mars is $1.98\times 10^{11}\ m$ from the Earth.
