Velocity = distance divided by time / Velocity = average speed over time /

Acceleration = (change of) velocity divided by time elapsed

Change in velocity = final velocity "minus" initial velocity divided by time elapsed

Takes her 60 seconds to do what? Travel 1 mile? Travel 10 miles?

Velocity is speed in a particular direction. Usually miles per hour or metres pet second . So that means that velocity is distance divided by time. Displacement is a distance measured in miles, metres etc. And is the difference between the starting position and the finishing position.

Constant velocity is a measure of distance traveled per unit of time at a uniform speed, such as miles per hour or feet per second. Constant acceleration is a measure of a continuing increase in velocity per unit of time, as when a car speeds up from 30 miles per hour to 40 miles per hour in 5 seconds, then from 40 miles per hour to 50 miles per hour during the next 5 seconds. It will then have had a constant acceleration of 10 miles per hour per 5 seconds.

velocity=distance/time for uniform velocity. You need units for both the time and the distance to get a correct answer. Example: the speed limit is 65 miles/hour

If air resistance is not considered, then a penny dropped from rest will accelerate 9.8 m/s² {on Earth}. Distance traveled is ½at², and velocity is at. After 2 seconds, it will have traveled 19.6 meters {about 64 feet} and reach a velocity of 19.6 m/s {about 44 miles per hour}.

Speed is simply how fast something is moving. Velocity is the rate that the object changes position. Imaging taking one step forward and one step back. The speed at which you do this may be 2 miles per hour but the velocity is zero because there is no change in position.

You cannot answer this question without knowing(at least the very least) velocity

Velocity = Distance ÷ Time : therefore Time = Distance ÷ Velocity. Time = 265 ÷ 65 = 4.0769 hours = 4 hours 4 minutes 37 seconds (approx)

Velocity (Speed) = Distance ÷ Time. : Time = Distance ÷ Velocity Time = 59 ÷ 85 = 0.6941 hours = 41 minutes 39 seconds (approx)

Speed (ex: meters/second, miles/hour)

The acceleration cannot be determined with this information. The beginning and ending velocity needs to be known. You can determine her average velocity, however. average velocity = displacement/time = (9mi - 3mi)/3s = 6m/3s = 2m/s

Using 32 ft/sec2 as the acceleration due to gravity, it would be 0.0303.. miles per sec.

Speed is the size of velocity. But velocity also has a direction. "30 miles per hour" is speed. "30 miles per hour north" is velocity.

60 miles in 5 seconds equals 12 miles per second. 12 x 60 =720 miles per minute. 720 miles per minute x 60 minutes per hour = 43,200 miles per hour, which is not physically possible for any living creature (mach 56).

Acceleration = change in velocity/change in time Acceleration = 96 miles per second - 32 miles per second/8 seconds = 8 miles per second per second or, better expressed 8 mi/s^2 ---------------

Velocity = Distance ÷ Time, therefore Time = Distance ÷ Velocity. Time = 12 ÷ 35 = 0.343 hours or 20mins 34 seconds approximately.

More accurately, velocity is a change in an object's position in a specified direction with time. So while you'd say in every day language that the car has a speed of 60 miles per hour, in physics you'd say the car's velocity is 60 miles per hour North/South/East/West.

Escape velocity is the velocity needed to escape the gravitational pull of a body. The escape velocity of the Earth is about 7 miles per second. The escape velocity of the Sun is about 25 miles per second.

Acceleration is the derivative of velocity with respect to time. What that means is, if you have a graph with time on x axis and velocity on the y axis, the slope of the line at a point in time is the acceleration at that same point in time. if your velocity is a linear function of time (a straight line -- not curvy) you can find the acceleration in this way. pick a time value, we'll call it t1. pick another time value, we'll call it t2. find the velocity associated with t1, we'll call it v1 v1=v(t1) find the velocity associated with t2, we'll call it v2 v2=v(t2) acceleration = (v2-v1)/(t2-t1) and your units will be your units of velocity divided by the units of time. For example, if you're measuring velocity in miles per hour (mph) and time in seconds, your units will be miles/(hours*seconds). If you're using meters per second and seconds, it will be meters/(seconds^2). Note that velocity is a vector quantity (it has a direction associated with it) and so is acceleration. Having non-zero acceleration means there will be a change in velocity, however, it does NOT NECESSARILY mean there will be a change in SPEED (which is the magnitude of velocity).

velocity=500 miles per hour

Velocity is speed and its direction. "30 miles per hour" is a speed. "30 miles per hour north" is a velocity". "30 miles per hour north" and "30 miles per hour south" are identical speeds but different velocities.

Velocity is speed with a direction. For Example 30 Miles/hour East would be velocity.
