Answer:

Explanation:
One of the first propulsion characteristics given in the example is that all engines are equal.
In this way if we have 4 engines running at the same time, it means that its capacity is 100%.
Under this premise, if 100% is found, the Jet is capable of reaching a speed of 8.7m / s ^ 2.
However, the question is, what would happen if 2.4 "Engines" now work.
To do this then we make a simple equivalence,
If 4 engines is the equivalent of 100%, when would it be 2.4 engines?

In this way it would mean that the body could be driven to 60% of its total.
