As a result of his observations, Roemer concluded that eclipses of lo by Jupiter were delayed by 25.2min during a 6 months period as the Earth moved from the point its orbit where it is closest to Jupiter to the diametrically opposite point where it is farthest from Jupiter. Using R= 147.0x106 km as the average radius of the Earth's orbit around the Sun, calculate the speed of light from these data. State your result in km/s to the nearest km/s
