Idk what steps to follow thru with! The majority of my tests will include questions like this... can you please list steps or procedures?

A tower resturant in Sydney, Australia, is 300 meters above sea level and provides a 360 degree panoramic view of the city as it rotates every 70 minutes. A tower resturant in San Antonio TX is 750 ft tall. It revolves at a rate of one revolution per hour.

a. In a day, how many more revolutions does the resturant in San Antonio make than the one in Sydney?

b. In a week, how many more degrees does a speck of dirt on a window of the restuarnt in San Antonio revolve than a speck of dirt on the window of the resturant in Sydney?

Please help! I have no idea how to do these kinds of problems and my test is monday.
