Because that's "time-travel velocity". There's no real logical reason why that speed would be necessary for time travel, if that's what you're asking. It's just what the filmmakers made up. They chose 88 mph because they thought it was "easy to remember".
Time travel is not realistic; it cannot happen unless one is going fast enough (e.g. close to light speed) such that significant time dilation occurs.
In the popular 1985 film Back to the Future, the DeLorean needed to go 88 mph (and 1.21 gigawatts) to travel back in time. Doc stole plutonium to power the time machine's flux capacitor and sent Marty back to 1955.
turn on the flux capacitor and reach 88 miles an hour
Approximately 20 to 24 miles per hour.
45 miles per hour
One mile is 1.6 km, you do the math.
The speed of the Delorean in the movie titled Back to the future had to reach 88 miles per hour before it could transport itself and the passengers back in time.
2 Miles An Hour.
750
It's about 1 hour to get to where ever u need to go and back.
About 50 minutes.
15 miles per hour
1,000,0000 miles an hour
The Golden Hour of the Future was created in 1977.
No. "Miles per hour" is a speed. An acceleration might be "Miles per hour per hour", or "miles per hour squared".
They had better be doing 90 miles per hour, otherwise the horse comes apart in the middle.
Assuming that the fly is in the car, then yes, it would also be travelling at sixty miles per hour. This is because when the car travels sixty mph, inside, the back of the car pushes the air inside to travel at the same approximate speed. The air then pushes the fly to travel at sixty miles per hour. If the front and back of the car were open (windshield and back window), then the air inside the car would not be moving, although since you would be travelling at sixty miles per hour, it would seem that the air is moving back.
At 1 mile per hour it is 55 hours, at 2 miles an hour it is 27.5 hours at 5 miles an hour it is 11 hours at 55 miles an hour it is 1 hour at 60 miles an hour it is 55/60 hour or 55 minutes at 120 miles an hour it is 27.5 minutes at 550 miles an hour it is 6 minutes etc
