Need expert guidance on whether it is reasonable not to assume constant work rates in this question. More generally, what's the best practice for assuming constant rates - should we not assume a constant rate unless stated otherwise? Many thanks in advance!

No, you cannot assume that the machines operate at constant rates. The question is flawed and badly written. Ignore it and move on.
