The approximate distance between Mars and Earth is about 1.34 × 108 miles. How many seconds would it take for TV pictures transmitted from the Viking space vehicle on Mars's surface to reach Earth? Enter your answer in scientific notation.

Respuesta :

Answer:

Time taken from transmission = 719.61 seconds or  11.99 minutes

Explanation:

Given data:

The distance between the mars and the earth = 1.34 × 10⁸ miles

Now, converting the distance into meters

1 mile = 1.61 km = 1610 m

thus, we have

1.34 × 10⁸ miles = 1610 × 1.34 × 10⁸ m = 2.1574 × 10¹¹ m

Now, the picture will travel with the speed of light i.e 2.998 × 10⁸ m/s

also,

Time = Distance/speed

thus we have,

Time taken from transmission = (2.1574 × 10¹¹ m)/(2.998 × 10⁸ m/s)

or

Time taken from transmission = 719.61 seconds or (719.61/60 = 11.99 minutes)
