Question

A man dive 2 meter and similarly awomen also do but women is 2 sec ealiar than man.the speed of the women is 15 km/hr what is the speed of the man?​

Answer 1

Step-by-step explanation:

let speed of man be x

Time taken by man=2/x

speed of women=15km/hr=15×(5/18)=25/6 m/sec

time taken by women =2/(25/6)=12/25sec

A/q 2/x -12/25=2

1/x=1+6/25

x=25/31 m/sec

(25/31)× (18/5)

x=90/31 km/hr
