Question

pls see attached pic...thank you.

Answer 1

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
