Fastest to slowest: 5.0 m/s, -10.0 m/s, 520.0 cm/s, 18.0 cm/s ,2.0 cm/s

Given : We have given sets of speed 5.0 m/s, -10.0 m/s, 520.0 cm/s, 18.0 cm/s ,2.0 cm/s .

To Find : Order the given speed from fastest to lowest .

Solution :

First of all we have to convert all the given speed in same units .

We know , 1 m = 100 cm .

Therefore , speed in units cm/s is :

500 cm/s , -1000 cm/s , 520 cm/s , 18 cm/s , 2 cm/s .

We know , that -ve and +ve sign only indicates the direction .

So , comparing their magnitude , we get the order as :

-1000 cm/s , 520 cm/s , 500 cm/s , 18 cm/s , 2 cm/s .

Hence , this is the required solution .
