Suppose that it takes about 3 days for a space vehicle to travel from Earth to the moon. About how long would it take the same space vehicle traveling at the same speed to reach Pluto?
look up the distance to the moon.
Divide that by 3 to get the rate per day of the space vehicle
look up the distance to Pluto
divide that distance by the rate you found above to get the time.
