Answer:

The ratio is - 4:3:1

Step-by-step explanation:

You have to understand the pattern.

Answer 2

Given,

The ratio of the speeds of three persons waking from place A to place B is 3:4:12.

To find,

The ratio of the time taken by all of them to reach place B.

Solution,

We can simply solve this mathematical problem using the following process:

As per the question;

let us assume that the speeds of three persons waking from place A to place B are 3x, 4x, and 12x units respectively.

Also, let the distance between point A and point B be equal to d units.

Mathematically,

Speed (s) = Distance traveled (d) / time taken (t)

=>Time taken(t) = Distance traveled (d)/Speed (s)

Now,

Time taken by the first person to reach point B

= Distance traveled (d)/Speed (s)

= d/3x

Time taken by the second person to reach point B = Distance traveled (d)/Speed (s)

= d/4x

Time taken by the third person to reach point B

= Distance traveled (d)/Speed (s)

= d/12x

The ratio of the time taken by all of them to reach place B = d/3x:d/4x:d/12x

= 1/3:1/4:1/12

= 4:3:1

Hence, the ratio of the time taken by all of them to reach place B is 4:3:1.
