Speed Item

The following list of items to slow down. coversion of meters per second?

List the following items in descending order of speed, highest to lowest: (A) A wind-up toy car that moves at 2.5 to 0.16. (B) A soccer ball rolling 2.7 on 0.55. (C) A bicycle traveling at 0.70 in the 7.5 × 10-2. (D) A cat that runs 8.0 to 2.2. Please tell me how u raise the problem and find the answer, thanks!

Since your question is not clear what are those numbers indicate because they do not put any units (meter, second, feet, inches, hours ?????) Anyway, I am assuming that the movement of each element is reported in meters and seconds. Therefore the car is traveling at 0.16 meters 2.5 seconds. This means the car is moving at a speed of 0.064 m / s. This is accomplished by dividing the distance traveled by the time needed to cover that distance. Therefore 0.16/2.5 = 0.064 Following the same rule, other travel goods in the following speeds: – ball Football: 2.7 m / 4.9 m = 0.55s / s – the bike: 0.70m / 0.075s = 9.33 m / s – Cat: 8.0 m / 2.2s = 3,636 m / s therefore Articles will listed in the following descending order of speed: C.bicycle, ball B.soccer, D.cat, courtesy A.toy
