5m - 5 second

Explanation:

can you please say, which school you are from

Answer 2

112 km/h = 31.11 m/s

40 km/h = 11.11 m/s

56 km/h = 15.56 m/s

19 km/h = 5.28 m/s

11 km/h = 3.06 m/s

40 km/h = 11.11 m/s

0.27 km/h = 0.075 m/s

0.05 km/h = 0.0139 m/s

• The most crucial scientific notion is measurement. Base or physical fundamental units are used to quantify a wide range of quantifiable quantities. One such measurable metric is speed, which calculates the ratio between the distance an object travels and the time needed to cover that distance.
• When an object travels the same distance in the same amount of time, it is said to be moving at a uniform speed. When an object travels a different distance at regular intervals, it is said to have variable speed. Average speed is the constant speed determined by the ratio of the total distance travelled by an object to the total amount of time it took to travel that distance. Instantaneous speed is the speed of an object when it is moving at any given moment and has a changing speed.

Here, according to the given information,

• 112 km/h = 31.11 m/s
• 40 km/h = 11.11 m/s
• 56 km/h = 15.56 m/s
• 19 km/h = 5.28 m/s
• 11 km/h = 3.06 m/s
• 40 km/h = 11.11 m/s
• 0.27 km/h = 0.075 m/s
• 0.05 km/h = 0.0139 m/s

Hence, the table is,

• 112 km/h = 31.11 m/s
• 40 km/h = 11.11 m/s
• 56 km/h = 15.56 m/s
• 19 km/h = 5.28 m/s
• 11 km/h = 3.06 m/s
• 40 km/h = 11.11 m/s
• 0.27 km/h = 0.075 m/s
• 0.05 km/h = 0.0139 m/s
