Answer:

Option B, It will run out of fuel after 2 hours.

Explanation:

Given -

For a 10 hour flight , amount of fuel used = 150000

1 liter of fuel = 0.803 Kg

So, 24,090 kg of fuels in liters

= \frac{24,090}{0.803} \\= 30,000 liters

150000 liter of fuel lasts for 10 hours

1 liter of fuel lasts for \frac{10}{150000} hours

and 30000 liter of fuel lasts for

\frac{10}{150000} * 30000\\= 2

Thus, option B is correct
