I'm not sure if my calculations are correct but here's how I did it. Time taken to complete the journey: Raju=8hrs Rob=6hrs Time taken for each of them to reach point P/midpoint: Raju=4hrs Rob=3hrs Time into their journey that they meet:- (4+3)/2 =3.5hrs Now we know that Rob=56km/30mins =56*2km/hr =112km/hr We can now calculate the length of the whole journey:- 112km*6 =672km And finally, we can calculate the speed which Raju travels:- Raju=672km/8hrs =84km/hr
