4) Two straight roads R1 and R2 diverge from a point A at an angle of 120 degrees. Ram starts walking from point A along R1 at a uniform speed of 3km/hr. Shyam starts walking at the same time from A along R2 at a uniform speed of 2km/hr. They continue walking for 4 hours along the respective roads and reach points B and C on R1 and R2 respectively. There is a straight path connecting B and C. Then Ram returns to point A after walking along the line segments BC and CA. Shyam also returns to A after walking along line segments CB and BA. Their speeds remain unchanged. The time interval (in hours) between Ram’s and Shyam’s return to the point A is (a) (10√19 + 26)/3 (b) (2√19 + 10)/3 (c) (√19 + 26)/3 (d) (√19 + 10)/3 (e) none of the foregoing
