A spaceship has a speed of 500000 meters per second. Calculate, in scientific notation, the speed in km per hour.
500000 m = 500 km
1 second = 1/3600 hour
so 500000m/sec
= (500/[(1/3600)] km/h
= 1800000 km/h
= 1.8 x 10^6 km/h
1 second = 1/3600 hour
so 500000m/sec
= (500/[(1/3600)] km/h
= 1800000 km/h
= 1.8 x 10^6 km/h
