Problem: In August 2011, the Juno spacecraft was launched from Earth with the mission of orbiting Jupiter in 2016. The closest distance between Jupiter and Earth is 391 million miles.If it takes 5.0 years for Juno to reach Jupiter, what is its average speed in mi/hr over this period?

FREE Expert Solution

We have to calculate the average speed of Juno spacecraft in mi/h units.


Speed is defined as distance traveled per unit time.

speed = distancetime


We will solve this problem through these steps:

Step 1: Convert distance form million miles to miles.

Step 2: Convert time from years to hours.

Step 3: Calculate speed of the spacecraft.
