Convert distances into miles and feet

Question

earths diameter 12,760 km. The moons diameter is 3,475 km. Convert these distances into miles and feet. (Hint: 1 km is about 0.62 miles and 1 mile is 5,280 feet)

Answer 1

EARTH: 12,760 km(.62 mi/1 km) = 7911.2 miles

7911.2 mi(5280 ft/1 mi) = 41,771,136 feet

 

MOON: 3475 km(.62 mi/1 km) = 2154.5 miles

2154.5 mi(5280ft/1 mi) = 11,375,760 feet
