Rate = distance / time. Therefore this is 100 / 4 cm per second, or 25 cm per second. This is 0.56 miles per hour; or 0.35 km per hour.
The average speed is 5 metres per second.
Speed = distance/time So speed = 100/5 = 20 Answer: 20m/s.
8ms-1
10 miles/second!
The average speed of the object over the 15 seconds (s) is equal to the distance travelled divided by the time taken. Therefore the speed of the object = 27/15 or 1.8 metres per second (m/s) It is important to note that this is the average speed and not the speed at any particular point in time. The object's speed can also be expressed in km/h by multiplying our answer by 3.6. So object's speed = 1.8 * 3.6 = 6.48 km/h
The average speed is 5 metres per second.
Speed = distance/time So speed = 100/5 = 20 Answer: 20m/s.
8ms-1
Th eobject traveled 82 meters in 42 seconds, so average speed is 82/42 = m/s = 1.95 m/s
3 m/s

The object's speed can also be expressed in km/h by multiplying our answer by 3.6. So object's speed = 1.8 * 3.6 = 6.48 km/h
The Average Speed means the total distance the object travels and the overall time it takes.
4 miles per second
The object is moving at the speed of 50 ms-1 .
it helps a lot
You use the formula speed = distance/time
