it is about 384,750 kilometers from earth to the moon. it took the apollo astronauts about 2 days and 19.5 hours to fly to the moon. how fast did they travel?
We know, speed = Distance / Time
d = 384,750 Km
t = 2 days, 19.5 hours = 48+19.5 = 67.5 hour
Substitute their values,
s = 384,750 / 67.5
s = 5700 Km/h
In short, Your Answer would be 5700 Km/h
Hope this helps!
The speed defines the movement of an object with respect to time. The speed of the astronauts is 5700 km/hr.
Given that the distance between the earth and moon is 384750 km. The time taken by the astronauts is 2 days and 19.5 hours.
Let convert the total time taken by the astronauts into hours.
Time \(t= 2\times 24 + 19.5 \;\rm hrs\)
Time \(t = 67.5 \;\rm hrs\)
Now the speed of the astronauts is,
Speed = Distance /Time
\(s = \dfrac {d}{t} \;\rm km/hr\)
\(s = \dfrac {384750}{67.5}\)
\(s = 5700 \;\rm km/hr\)
Hence we can conclude that the speed at which the astronauts traveled to the moon is 5700 km/hr.
