orbital speed of mars! help!?
Mars is 230 million km from the sun. It completes one orbit in a period of approximately 687 days. Calculate the orbital speed of Mars in mph.
OK so gave me the formula which 2*pi*r/ Period r= distance from the planet to the sun. and cirmumference = 2*pi* r
So i set it up 2*3.1416* 150E6 km /16488 hours (mars hours)
= 57161.57 km/hr then convert to mph 57161.57km hour/1.60km =35725.98 mph
