Acc. to the question both of them travel the same distance. Let it be d
d= 60*t1 and d= 75*t2. Rishabh time= t1 and Ramesh time= t2
Also t1= t2+30; ---- (i)
So 60*t1= 75*t2 => t1= 5/4t2 putting this t1 value in eq.(i)
We get 5/4t2-t2=30 hence t2= 2 hrs.
So t2 is the time of Ramesh time hence 6:30p.m+ 2 hrs= 8:30pm
d= 60*t1 and d= 75*t2. Rishabh time= t1 and Ramesh time= t2
Also t1= t2+30; ---- (i)
So 60*t1= 75*t2 => t1= 5/4t2 putting this t1 value in eq.(i)
We get 5/4t2-t2=30 hence t2= 2 hrs.
So t2 is the time of Ramesh time hence 6:30p.m+ 2 hrs= 8:30pm
