Question

a certain distance is covered at ceratain speed. if the half distance covered in double time , the ratio two speed is

Answer 1

Answer:

1:4

Step-by-step explanation:

Let the distance covered be x;

Lett the time taken be t;

∴ The speed will be x/t.............(1)

Now, according to queation;

The distance becomes half, let it be x/2;

The time becomes double , let it be 2t;

∴ the speed will be $\frac{x/2}{2t}$

= x/4t..........(2)

Now, dividing (1) and (2) , to get the desired ratio of speed

∴ ratio = $\frac{x/t}{x/4t}$

ratio = 4 : 1
