Answer» Correct Answer - Option 4 : 15 : 20 : 12

Given:

Three person are walking from A to B.

Their speed are in the ratio = 4 : 3 : 5.

Formula used:

Time = Distance/Speed 

Calculation:

Time = 1/4 : 1/3 : 1/5 

Let L C M of 4, 3, and 5 = 60

Time (1/4)× 60 : (1/3)× 60 : (1/5)× 60

∴ The time ratio will be 15 : 20 : 12.
