how do I solve how much time does it take for a satellite moving 15000 miles per hour travel to travel once around the earth 249
iogann1982 [59]

Answer:

The time taken by the satellite to orbit earth at its surface, t = 1.66 hr

Explanation:

Given data,

The velocity of the satellite, v = 15000 miles/hr

The distance of travel, d = 24901 miles,

It is equal to the circumference of earth,

So the time taken by the satellite to orbit earth at its surface,

                           v = d/t

                            t = d/v

Substituting the given values in the above equation,

                            t = 24901 / 15000

                              = 1.66 hr

Hence, the time taken by the satellite to orbit earth at its surface, t = 1.66 hr
