Thanks glad it could help.

By the way in your elaborated solution you added some extra steps that can be avoided.

For avg speed it will be = Dtotal/(0.24Dtotal/36 + 0.76Dtotal/48)

the only variable in here is Dtotal which cancels out.

What you did was to multiply V1 * T1 and also V2 * T2 to get Dtotal. This extra step can be avoided. I hope it makes sense and is clear

I apologize for my formatting as I solved the question using the mobile, I will edit it later from the computer.

I tried to do this without any calculation:
if we have the individual average speeds and the ratio of the distances in this case outbound distance is 76% and inbound is 24 % then we can plug in numbers for distance and get the average speed for the entire journey. Hence3 answer is "A"Please correct me if I am wrong
