im thinkin you need to go hyperspeed
You will need to travel at an average of 25 miles ÷ 2 hours = 121/2 mph.
56 mph
120 mph
42.86 miles per hour.
At sea level it needs to travel at 340m/s.
bobcats travel fast,but they only go up to 57 m.p.h.
If you went at a speed of a mile a minute, or 60 mph, you would travel 25 miles in 25 minutes. For 10 miles in this time you only have to travel at 2/5 of that speed, or 24 mph.
Unfortunately, the ability to travel back in time is not currently possible. It is unknown to us what time travel requires, be it speed, distance, location, or what is capable of making the trip, if such a trip is even possible.
If my calculations are right you need to travel 20 miles per hour to reach ten miles in thirty minutes.
Faster than the speed of light, in theory.
6.29*60/25 = 15.096 mph
In theory, to travel back in time, you would need to exceed the speed of light, which is not currently possible based on our understanding of physics. Time travel into the past is still considered a concept mostly explored in science fiction rather than reality.
