I was wondering how long would it take to reach Jupiter if you traveled at 100 km/h (freeway speed)?
Question Date: 2018-05-21
Answer 1:

Jupiter is about 588 million kilometers away. If you recall what you know about rates of speed, time, and distance, we can figure this out using units and compound fractions (which I’m sure are your favorite!)

If we travel at 100 kilometers per hour, we can write that as a fraction: 100 kilometers/hour. The numerator is kilometers (km) and the denominator is hours (hr). If we want to know how many hours it takes to drive a distance, we can set up math equation:

TimeToDrive (hrs) = DrivingDistance (km) / DrivingSpeed (km/hr)

If you reduce the compound fraction on the right (km/km/hr), the km cancel out and the hr comes up to top, so get an answer in hours.

If we plug in your question to this equation, we get:

TimeToDrive (hrs) = 588,000,000 (km) / 100 (km/hr) = 5,880,000 hours = 245,000 days = 670.8 years ~ 9 human life spans.

That’s a lot of time! If you wanted to get to Jupiter before your great, great, great, great, great, great, great grandchildren die, then I recommend finding a faster way to travel. Let me know what you come up with!
