Question

The Voyager 2 spacecraft was launched on August 20, 1977. It is now Tracy at a velocity of about 12,000 meters per second. Given that 1 kilometer is approximately 0.62 miles, how fast is Voyager 2 traveling in miles per hour?

Answer 1

To find the speed of Voyager 2 in miles per hour, we need to convert the given velocity from meters per second to miles per hour. We can use the following conversion factors to do this:

1 kilometer = 1000 meters

1 kilometer = 0.62 miles

1 hour = 3600 seconds

We can multiply the given velocity by these conversion factors in the appropriate order to get the speed in miles per hour. The calculation is:

Speed in miles per hour = (12,000 meters / second) x (1 kilometer / 1000 meters) x (0.62 miles / 1 kilometer) x (3600 seconds / 1 hour)

Speed in miles per hour = (12,000 x 0.62 x 3600) / (1000 x 1 x 1)

Speed in miles per hour = 26,784 miles per hour

Therefore, Voyager 2 is traveling at a speed of 26,784 miles per hour. This is very fast, considering that the speed of sound is about 767 miles per hour and the speed of light is about 670,616,629 miles per hour. You can learn more about Voyager 2 . I hope this helps you understand how to convert units of speed.
