Question

The space shuttle Endeavor is launched to an altitude of 400,000 m above the surface of the Earth. The shuttle travels at an average rate of 750 m/s. How long will it take for Endeavor to reach its orbit?

Question 4 options:


0.53 s


533.3 s


300,000 s


400,000 s

Answer 1

We can simply use:
speed = distance / time
To calculate the time, since speed and distance are known.

time = distance / speed
time = 400,000 / 750

time = 533.3 seconds
