Arocket moves through outer space a 12,000 m/s. at this time, how much time would be required to travel the distance from earth to the moon, which is 380,000 km?

12000 m/s = 12 km/s. Now to go 380000 km, it will take some time. How much time is given in the formula 12km/s. You go 12 kilometers every second. So you take  and that gives you 31,666.666 seconds. 

12,000 m  =  12 km

                     (380,000 km) / (12 km/sec)

                 =  (380,000 / 12)      sec

                 =      31,666-2/3 seconds

                 =      8 hours  47 minutes  46.7 seconds 

Wow good luck with that answer
