3
Orbital distance= 2 x 3.14 x 93,000,000 miles = 584,040,000 miles Orbital distance per day= miles = 1,600,000 miles Orbital speed per hour= mph = 66,667 mph

4
The Moon Distance from Earth = 240,000 miles Orbital distance = 2 x3.14 x240,000 = 1,507,200 miles Orbital period = 28 days Orbital distance per day= miles = 53,800 miles Orbital speed per hour= mph = 2240 mph

5
