1000 seconds is 16 2/3 minutes
1,000 miles
It takes 2.045 seconds.
139 yards per 25.75 seconds is probably 11.04 miles/hour.
It would take: (220/100) times 9.2 = 20.24 seconds
1000 inches = 83.3 feet = 27.8 yards
At 1000mm per second it will take 91.44 seconds (1 minute 31.44 seconds) to travel 100 yards.
40.9 seconds.
There is no one answer, since there is no one bullet. The drop of a bullet is a function of the speed- how long it took to get to 1000 yards. Some bullets will not TRAVEL 1000 yards. All other things being equal, the faster bullet will drop less.
There is no one single best caliber, but to get an answer, you need to be a little more specific. Rifle or handgun? Define long distance. 50 yards? 100 yards? 1000 yards?
There are 3 feet in one yard. Therefore, 1000 feet is equal to 1000 / 3 = 333.3 recurring (that is, 333.333...) yards.
