Question #1432

Average speed equals distance divided by time. On a journey to the Alpha Centauri star system, a space probe travels a distance of 4.12×10[sup]16[/sup] meters in 1.73×10[sup]10[/sup] seconds. (a) Find its average speed in meters per second. (b) How long did the journey take in years? Use 365.24 days per year

Expert's answer

a) V = S/t = 4.12×10^{16} [m] / 1.73×10^{10} [s] = 2381502.89 m/s

b) In the year there is 365.24 days, in the day there is 24 hours, in one hour - 60 minutes, in one minute - 60 seconds; thus

1.73*10^{10}/(365.24*24*60*60) = 548.22 years.

b) In the year there is 365.24 days, in the day there is 24 hours, in one hour - 60 minutes, in one minute - 60 seconds; thus

1.73*10
