18,000 meters per hour or 18 km/h .

It is more usual, scientifically, to express speed in metres per second (m/s, or ms-1) as these are the SI units for distance and time, respectively. It also makes the maths a heck of a lot easier to work out, as you don't need to convert seconds to hours!
100 m in 20 s is the same as 5 m in 1 s (100 / 20 = 5). So the answer is also 5 ms-1
The object is moving at the speed of 50 ms-1 .
If an object travels at an average speed of 31 meters per second, you can calculate the distance it would cover in 30 seconds using the formula: distance = speed × time. Thus, distance = 31 meters/second × 30 seconds = 930 meters. Therefore, the object would travel 930 meters in 30 seconds.
To find the time it takes to travel 100 meters at an average speed of 0.5 meters per second, you can use the formula: time = distance/speed. Plugging in the values, time = 100 meters / 0.5 meters per second, which equals 200 seconds. Therefore, it will take 200 seconds for the object to move 100 meters.

The average speed is 5 metres per second.
The object is moving at the speed of 50 ms-1 .
If an object travels at an average speed of 31 meters per second, you can calculate the distance it would cover in 30 seconds using the formula: distance = speed × time. Thus, distance = 31 meters/second × 30 seconds = 930 meters. Therefore, the object would travel 930 meters in 30 seconds.
Average speed = (total distance) / (total time for the distance) =(16 + 16) / (4 + 2) = (32/6) = 51/3 meters per second
To find the time it takes to travel 100 meters at an average speed of 0.5 meters per second, you can use the formula: time = distance/speed. Plugging in the values, time = 100 meters / 0.5 meters per second, which equals 200 seconds. Therefore, it will take 200 seconds for the object to move 100 meters.
320 meters
The object will be moving at 14.7 meters per second. 1.5 seconds X 9.8 meters per second squared(the gravitational constant). This assumes that the object's original velocity is zero.
The average speed is 5 metres per second.
3.00 m/s
To find the speed of an object, you can use the formula: speed = distance/time. In this case, the object travels 100 meters in 50 seconds. Therefore, the speed is 100 meters ÷ 50 seconds = 2 meters per second.
The speed of the object would be 3 meters per second (45 meters ÷ 15 seconds).
To determine average speed, you need to know what distance the object traveled in meters over how long it took the object to travel that distance in seconds.
The velocity = (location at 40 seconds - location at 20 seconds)/20 in the direction in which the object is moving.
