1 mile = 5,280 ft 87 miles in 1 hour = 87(5,280 ft) in 3,600 seconds = 459,360 ft. That is 127.6 ft in 1 second. So in 12 seconds the distance traveled will be 1,531.2 ft (12 x 127.6)

Concrete is a mixture of cement , sand, gravel and water. A cubic yard of concrete is 3' x 3' x 3' . That's 3x3=9x3=27 . 27 cubic feet = 1 cubic yard . So it's 27 feet divided by 3 inches equals 108 sq ft!
As far as I know; to equal ft. and inches (366sq. ft. and 6 inches ) if you convert this iti is 366 divided in half to give you a 12 inch depth =183 cubic ft and divide by 3 to get cubic yards = 61 cubic yards
