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
8ms-1
The object is moving at the speed of 50 ms-1 .
The average speed is 5 metres per second.
IF the object begins from rest, then it travels 1.5 x 10^8 meters. (rounded)
I think it's 43,200 miles per hour, but I'm not sure

10 metres in 5 seconds; divide the distance by the time, 10/5= 2 metres per second
Speed = distance/time So speed = 100/5 = 20 Answer: 20m/s.
Just divide the distance by the time. This will give you the speed in meters/second. If you want to convert that to kilometers/hour instead, multiply the result by 3.6.
Distance = Velocity*Time = 25.5*85 metres = 2167.5 metres.
