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
7.5
The speed of the object would be 3 meters per second (45 meters รท 15 seconds).
8ms-1
3.00 m/s
The object is moving at the speed of 50 ms-1 .
The object will move a total distance of 80 meters, which is calculated by multiplying the speed (10 m/s) by the time (8 seconds).
The speed of the object is 5 m/s. Speed is calculated as distance divided by time, so 20 meters/4 seconds = 5 m/s.
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
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.
10 metres in 5 seconds; divide the distance by the time, 10/5= 2 metres per second
