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.Once Juno reaches Jupiter, what is the minimum amount of time it takes for the transmitted signals to travel from the spacecraft to Earth?

FREE Expert Solution

We’re being asked to determine the minimum amount of time it takes for transmitted signal to travel from the spacecraft Juno to Earth.


Signals from outer space are transmitted using electromagnetic waves. Electromagnetic waves travel with the speed of light = 3.00x108 m/s.


 For this problem, we need to do the following steps:

Step 1: Convert the distance between Jupiter and Earth from miles to meter.

             1 mile = 1.609 km

             1 km = 103 m

Step 2: Multiply the distance to the speed of light to calculate for the time it takes for transmitted signal to travel from Juno to Earth.
