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 average speed is 5 metres per second.
The velocity = (location at 40 seconds - location at 20 seconds)/20 in the direction in which the object is moving.
Speed = distance/time So speed = 100/5 = 20 Answer: 20m/s.
The object is moving at the speed of 50 ms-1 .
The total distance covered is 32 meters (16 meters + 16 meters). The total time taken is 6 seconds (4 seconds + 2 seconds). Therefore, the average speed of the object is 32 meters / 6 seconds = 5.33 meters per second.
If an object moves 50 meters in 5 seconds, its average speed is 50/5 = 10 meters per second.
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 calculate the velocity of a moving object, you divide the change in its position by the time it took for that change to occur. The formula for velocity is velocity equals displacement divided by time taken (v = d/t). The resulting value will have units of distance traveled per unit of time (e.g. meters per second).
The speed of the object would be 3 meters per second (45 meters รท 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.
No, it can't. Average VELOCITY can be zero, though.
