There are 5280 feet in one mile. Therefore, 4000 feet is equal to 4000/5280 = 0.75 recurring (that is, 0.757575...) miles.
There are 5280 feet in one mile. Therefore in 4000 feet there are 4000/5280 miles. Cancel down by '10' Hence 400/528 Cancel down by ''8' 50/66 Cancel down by '2' 25/33 miles or in decimal 0.757575.... miles.
Best part of a mile, I think. 1,375 yards per mile.
21,120,000 feet.
4000 meters is about 13,123.36 feet high or 2.5 miles.
5280 feet = 1 mile 40000 feet = 40000/5280 = 7.57576 miles (5dp)
I'm thinking that's not what you wanted to ask but as written, the answer is 4000.
253440000 inches = 4000 miles
4000 millimeters = 13.12 feet.
4000 feet = 1.22 km, approx.
4000 kilometers = 13,123,359.6 feet.
1 fathom = 6 feet so 4000 feet = 4000/6 = 666.6667 fathoms.
