The square of the time of a planet's revolution around the sun in the year varies as the cube of its distance from the sun. find the time of the venus's revolution assuming the distances of the earth and venus from the sun to be 365/4 and 66 million meters respectively.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
