Quizplus · Accepted Answer

The distance from the Sun to Saturn is 9.5 AU, which is 9.5 x 1.5 x 10^8 km. The speed of the solar wind is 400 km/s. Time = Distance/Speed = (9.5 x 1.5 x 10^8 km) / (400 km/s) = 3.56 x 10^6 seconds, which is approximately 41 days.

The Speed of the Solar Wind Is Approximately 400 Km/s
