a = (vf - v0)/Δt
10 mph/s = (45 mph - 20 mph)/Δt
Δt = 2.5 s
As long as the 30 minute are spent driving in a straight line, the acceleration is zero.
It all depends upon the acceleration. A fast car can probably do it in under 10 seconds. Driving economically would take much longer. A jet plane can do it quicker.

It would be 3/8 of an inch long or wide.
It would be 5.5 times 12 = 66 inches

About .0011111 hours, or about 4 seconds.This is assuming the units are miles/(hour*sec), which converts to 36000 miles/(hour^2) as the acceleration.
Acceleration = Change in speed/Time Time = Change in Speed/Acceleration = 65mph/20mph per s = 65/20 seconds = 3.25 seconds
There is no such thing as 20 mph acceleration. 20 mph is a velocity. Acceleration is expressed as velocity per unit time e.g. mph per second or mph per minute etc.
A Cheetah can accelerate as fast as a Ferrari. In Numbers, it can accelerate from 0-100kph in just about 3 seconds, a few strides. The maximum speed of a Cheetah is 114km/h and it will mantain this speed for a short distance before stopping to rest for a long time to cool down. So the cheetah acceleration is unmatched, compared to the best sportscar available. (talking about 0-100km/h, the car would continue to accelerate after that, and the cheetah doesn't).
depends on how long it takes to accelerate from these speeds (45m/s-25m/s)/time(s)
The formula for finding time based on acceleration and speed is: (Delta)t = (Delta)v/a Change in time = change in speed / acceleration t = 75-15 / 20 t = 60 / 20 t = 3 seconds
Depends on the rate of acceleration (km / h) / second
In a relay race the acceleration zone is 10m long.
It would depend on the vehicle.
A bullet does not accelerate after it leaves the barrel of a gun. It will decelerate. You could say it accelerates, but the acceleration would be negative. The bullet is accelerated by expanding gas as it moves down the barrel, and after it leaves the muzzle, there is no more acceleration imparted from expanding gas. We also find that air friction (drag) is acting to slow it down. Think this one through and it becomes obvious.
How long it would take to get from Earth to Uranus depends on:What kind of propulsion system you haveHow much acceleration you can tollerateHow long you can tollerate high acceleration, if high acceleration is used.How much fuel your vehicle can carryWhether you want to be able to get back to Earth
