Question

Three cars travelled distance in the ratio of 1:2:3 if the ratio of the time of travel is 3:2:1, then the ratio of their speed is???

Answer 1

Let distance ratios be 1x 2x and 3x
Let time ratios be 3x 2x and 2x

Speed = distance × time

Speed of 1st car = 1x × 3x
Speed = 3x/hr

Speed of 2nd car = 2x × 2x
Speed = 4x/hr

Speed of 3rd car = 3x × 1x
Speed = 3x/hr

The ratio of speeds = 3:4:3

Ans : 3:4:3

Answer 2

Let the distance travelled by cars be 3x, 2x and x respectively

And the time taken by the cars be y, 2y and 3y

Speed of first car = 3x /y

Speed of second car = 2x/2y = x/y

Speed of third car = x/3y


Required ratio = 3x/y : x/y : x/3y

= 3 : 1 : 1/3

= 9:3:1
