Question

please anybody solve the no.13 sum ​

Answer 1

Answer:

if half of this distance is covered in double the time,the ratio of the two speed is 4:1

Answer 2

Answer:

4:1

Step-by-step explanation:

Let x km be covered in y hours.

Then, speed = x/y km/hr

In the second case,  x/2 km is covered in 2y hours.

New speed = $(\frac{x}{2}$×$\frac{1}{2y} )$ m/hr = x/4y km/hr

Ratio of speeds = x/y : x/4y =  4:1
