Question:In a aeroplane, the fuel burnt is directly proportional to the square root of its speed. If the aeroplane travels 800 km at a speed of 441 km/hr, the amount of fuel burnt is equal to 1250 litres. Find the distance travelled by the aeroplane, if 2000 litres of fuel was burnt while travelling at 784 km/hr. a:900 b:960 c:1200 d:1260

Pv Aaditya · Answer

For 800 km, the fuel burnt when travelling at 784 kmph = 1250*$$\sqrt{784/441}$$ = 1250*4/3
So, 5000/3 liters are required to travel 800 km
For 2000 liters, the distance that can be travelled = 2000*3/5000 * 800 = 960 km
