jetsons flying car

Question

Ondrea could drive a Jetson's flying car at a constant speed of 170.0 km/hr across oceans and space, approximately how long would she take to drive from the Sun to Pluto in years? (Assume Pluto is at its average distance of 5.9 × 10⁹ km from the Sun)

Answer 1

We are covering a distance of 5.9 x 10⁹ km at a speed of 170 km/hr.

time = distance / speed = (5.9 x 10⁹) / 170 = 34705882.35 , but this will give our time in hours.

We want years, so we divide by 24 hours/day and 365 days/year:

34705882.35 hours / 24 ≈ 1146078 days / 365 ≈ 3962 years
