During the first 6 years of its operation, the Hubble Space Telescope circled the Earth 37,000 times, for a total of 1,280,000,000 km. It takes the Hubble Space Telescope about 90 minutes to make one complete orbit. How fast is it traveling (in units of km/min)? Remember, distance = time x speed. Round your answer to the nearest integer and don't include the units for this answer.
