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.
