356 kilometres is a distance, not a speed. Therefore, the two units are incompatible.
Distance = Rate * Timeso,Rate(speed) = Distance/Time= 112 meters/4 seconds= 28 meters/second
Velocity is the rate of speed in a given direction. Therefore, the plane's velocity is 610mph NW.
This question is invalid. The speed needs to be a rate, not a measurement.
1,680/3 = 560 miles per hour

Constant speed occurs when an object travels at a steady rate with the same instantaneous speed for some period of time. This means that the object covers the same distance in equal intervals of time.
The rate at which a wave travels is called its speed. This speed depends on the medium through which the wave is moving - for example, sound waves travel faster in water than in air. The speed of a wave is typically measured in meters per second.

The speed at which an object travels at a steady rate for a period of time is called the average speed. It is calculated by dividing the total distance traveled by the total time taken to travel that distance. Average speed gives a general idea of how fast an object is moving over a given period.
The first step is to find out how long the airplane took before takeoff. If it travels at a uniform 2.45ms-2 acceleration and needs to get to 70ms-1 then this will take 70/2.45 = 28.57142857... seconds. The next step is to calculate the average speed. The plane starts at 0 and ends at 70, so the average speed will be 35ms-1. To find the distance travelled, we multiply the average speed (35) by the time taken (28.57142857...) and this gives 1,000. Thus, the plane travels for 1km before takeoff.
Distance = Rate * Timeso,Rate(speed) = Distance/Time= 112 meters/4 seconds= 28 meters/second
159.3333 mph (the digit 3 repeats indefinitely)
Flying with the jet stream, the plane's speed is its own speed plus the jet stream speed, totaling 80mph more than its usual speed. So, when it travels for 5 hours, it covers 5 hours x (its speed + 80mph). After leaving the jet stream, it flies at its own speed, without the jet stream speed. For the next 4 hours, it covers 4 hours x its speed. The total distance traveled during the entire trip is the sum of these two distances.
Velocity is the rate of speed in a given direction. Therefore, the plane's velocity is 610mph NW.
This question is invalid. The speed needs to be a rate, not a measurement.
If an object travels with constant acceleration, its speed will change at a constant rate over time. The object's speed will increase if the acceleration is positive, decrease if it is negative, and remain constant if the acceleration is zero.
