Can someone tell me if I'm right with this conceptual physics question?

The question reads:

If distance d has units of meters, and time T has units of seconds, does the quantity T+d make sense physically? What about the quantity d/T? Explain both cases.

I'm assuming that T+ d does not make sense physically because it is not dimensionally consistent. Whereas d/T is dimensionally consistent which could indicate velocity.

I'm new at physics, does this make sense? Is there a better way I could answer this?

    It makes sense. I'd reword the second one, something like "d/T has units of meters per second, consistent with speed and velocity." To me "dimensionally consistent" suggests you have an equation and that the units on the LHS are the same as on the RHS. IMO.
