The average distance from Earth to the Moon is 384,000 km. In the late 1960s, astronauts reached the Moon in about 3 days. How fast (on average) must they have been traveling (in km/h) to cover this distance in this time? Compare this speed to the speed of a jet aircraft (800 km/h).

They must have been traveling at 5333.33 km/h to cover that distance in 3 days.

That speed are 6,66 times higher than the speed of an aircraft jet.

Explanation:

d = 384000 km

t = 3 days = 3*24hr = 72hr

V = 384000km/72hr

V = 5333.33 km/h

comparison:

V1/V2 = 5333.33/800

V1/V2 = 6.66
