Answer 2

Answer:

Required difference is 20 litres.

Option B is the correct answer.

Step-by-step explanation:

Given,

Distance covered by the track is 1680 km.

The first truck averaged 14 km per liter of fuel for the trip.

And The second truck averaged 12 km per liter of fuel for the trip.

Fuel used by first track $= \frac{1680}{14} = 120$litres

Fuel used by second track $= \frac{1680}{12} = 140$litres.

So difference of use of fuel of two truck is$140 - 120 = 20$litres
