Final answer:
The question does not provide enough information to answer accurately.
Step-by-step explanation:
To determine how much fuel will be remaining when using all the holding fuel in your alternate, we need to know the initial amount of fuel available and the rate at which fuel is consumed. Unfortunately, the question does not provide this information. If you can provide the initial amount of fuel and the rate of fuel consumption, I would be able to assist you in calculating the remaining fuel.
