To find out how much fuel remains in the tank after the trip, we first need to convert all measurements to the same unit. We can convert the 350 milliliters to liters:
1 liter = 1000 milliliters 350 milliliters = \( \frac{350}{1000} = 0.35 \) liters
Next, we calculate the total amount of fuel used during the trip:
\[ \text{Total fuel used} = 145 \text{ liters} + 0.35 \text{ liters} = 145.35 \text{ liters} \]
Now, we can find the fuel remaining in the tank by subtracting the total fuel used from the initial amount of fuel in the tank:
\[ \text{Fuel remaining} = 600 \text{ liters} - 145.35 \text{ liters} = 454.65 \text{ liters} \]
So, the amount of fuel remaining in the tank is \( \text{454.65 liters} \).
