pproximately how long would she take to drive from the Sun to Pluto in years?

Question

Ondrea could drive a Jetson's flying car at a constant speed of 180.0 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

Hello Hollie!

constant speed of 180.0 km/hr

average distance of 5.9 × 10⁹ km

We want hours from this unit conversion. Since they are in the bottom of the speed measurement unit, we divide distance by speed. that will flip the unit and cancel out the distance component

km / (km/hr) → hr

5.9 × 10⁹ km / (180.0 km/hr ) = 3.28 x 10⁷ hr

to turn hours into years we need to follow this unit chain

3.28 x 10⁷ hr • ( 1 year/( 8760 hr )) = 3744 years
