Want this question answered?
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.

Constant Speed
A rocket

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.

This isn't really a computer-related question but speedis the rate at which something travels at a given interval of time.
Distance = Rate * Time or, for our purposes, Rate = Distance/Time Rate = 200 miles/4 hours = 50 miles per hour ==============
