Using SolveSys to solve equation with variable using unit

[Francois Vignon]

Sorry if it's a duplicate or already solved but I don't find ...

how can I use solvesys (on hp prime) to solve system with variable using units:
i.e.:
distance=time*velocity
distance in nmi, time in hour and velocity in knot

I know I can remove unit and it's done.

but if the velocity is in m/s, I must convert it before or adding a factor in equation.

I come from hp48 and on this one it's easy.

Can you help me ?

I’m not sure if this is what you’re looking for, but you can solve in CAS:

solve(10_nmi=5_h*x,x)

Returns

[2_nmi/h]

You can use USIMPLIFY if you get a mix of units like m*s/s -> m, and MKSA to go from nmi/h to meter-kilogram-second-ampere system.
