The object is moving at the speed of 50 ms-1 .
To calculate the speed of an object, you use the formula speed = distance/time. In this case, the object travels 100 meters in 20 seconds, so the speed would be 100 meters / 20 seconds = 5 meters per second. Therefore, the speed of the object is 5 m/s.
Speed = distance/time So speed = 100/5 = 20 Answer: 20m/s.
