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

`d=1.98* 10^(11)\ m`

Step-by-step 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* 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* 3* 10^8\\\\d=1.98* 10^(11)\ m`

So, Mars is
`1.98* 10^(11)\ m` from the Earth.
