Question

Three persons are walking from a place P to another place Q. If their speeds
are in ratio of 5:7:6, then the ratio of their time to reach Q is.........​

Answer 1

Ratio of speeds = 5 : 7 : 6

Therefore Ratio of times taken = (1/5) : (1/7) : (1/6)

                                                    = 42 : 30 : 35

Answer 2

Answer:

42:30:35

Step-by-step explanation:

speed= distance/time

if the distance is constant....

speed is inversely proportional to time..

Speed.Time=Constant=210 (L.C.M Of 5,7,6=210)

Arriving time of three persons (Time) =210/5:210/7:210/6

=42:30:35
