Yes, we need to know the context of the question- simplified exam question or real life. If the latter then we need more info such as whether the £0.28 figure includes kaw's salary (plus the on-costs for employers NI, pensions and maybe some ancillary costs- eg payroll fee, equipment, drinks, training, membership of association) and whether kaw is the only person involved in the production of these 1440000 units.
My guess is kaw wants to know 30000/1440000 but if so the employer's salary on- costs of maybe 25% (some say 40%) need to be added on
