One foot is equal to 0.0003048 kilometres. Therefore, 750 feet is equal to 750 x 0.0003048 = 0.2286 kilometres.
750 x 1.609 = 1206.75 kilometres

An example: A football travels at A speed unknown. Measure A distance for travel. Throw the ball and time it with A stopwatch. Take the feet and devide by seconds. 100feet, for 8seconds = 12.5 feet/per second. multiply 12.5 (feet) by 60 (seconds in A minute) =750 feet/per minute multiply 750 (feet) by 60 (minutes in an hour) = 45,000 feet/per hour. Divide 45,000 (feet) by 5,280 (feet in A mile) = 8.522 Miles/per hour This will work for any measuring scale, You just need to know all the different measurement steps. I.E. - feet in A mile, seconds in A minute, minutes in an hour. ECT.
If you traveled 25 miles in 2 minutes, your average speed was 25 miles per 2 minutes or 750 miles per hour. If your rate of deceleration was constant, your initial speed was two times 750 miles per hour or 1500 mph. I do not have enough information to determine your initial velocity because I don't know what direction you were going, and velocity is speed with direction.
The Earth travels at about 66000 miles per hour around the sun, much faster than the speed of sound which is about 750 miles per hour. Even as the Earth rotates, a point on the equator travels at a little over 1000 miles per hour so parts of the planet are faster than the speed of sound even without the orbit around the sun.

72 Miles per hour.

750*0.82=615 mph By the way, 1 mach is the speed of sound, which is 750 mph
About 110 miles per hour, from my experience.

It is: 750/2000 times 100/1 = 37.5%

Time = Distance/Speed = 750/55 = 13.6363.. hours - assuming you can keep up an average speed of 55 mph for more than 13 hours.
