13.33 km/hr

Let speed(in kmph) of Ramu=R and Shyamu=S, then
According to 1st condition: 60/R - 60/S = 2 => RS = 30S - 30R ---(i) and
According to 2nd condition: 60/S - 60/(3R) = 1 => RS = 60R - 20S ---(ii)
Comparing (i) & (ii), 30S - 30R = 60R - 20S => 5S = 9R
As we require 'R' so substituting S=9R/5 in Equation 60/R - 60/S = 2, we get 60/R - 60/(9R/5) = 2
=> R = 40/3 = 13.33
