The amount of gas Alex would need after 15 hours = 15 × 3.917
= 58.75 litres
An individual is referred to as unitary. Determining values in relation to a single unit is the goal of this strategy. For instance, if a car travels 44 kilometers on two liters of gasoline, we may calculate how many kilometers it will go on one liter of gasoline using the unitary technique.
Given every 10/3 hours Alex uses tank of gas = 6/7
By using unitary method we get
this implies every 1 hour the amount of gas which would be used by his = 10/3 ÷ 6/7
= 3.33 / 0.85
= 3.917
thus the amount of gas Alex would need after 15 hours = 15 × 3.917
= 58.75 litres
