Question

Joshua drove his car a distance of 356.2 miles, and it required 11.3 gallons of gasoline (petrol). How many liters of fuel will it take to go 100 kilometers.

Answer 1

Answer:

To cover 356.2 miles it required 11.3 gallons of gasoline (petrol).

in 1 mile it required 0.031723507 gallons of gasoline (petrol).

so, to cover 100 km it required 1.97122248 gallons of gasoline (petrol).

Answer 2

Distance

Distance travelled by car $= 356.2 \ miles$

Capacity of gasoline required to travel $= 11.3 \ gallons$

As we know that,

$1 \ mile = 1.609 \ kilometers$

$1 \ gallon = 3.785 \ litres$

So, distance travelled in  kilometers= $356.2\times 1.609=573.1258\ km$

Petrol used to travel in litres =$11.3\times 3.785=42.7705 \ litres$

Hence in 1 litre petrol $= \frac{573.1258}{42.7705}=13.40$

He can travel 13.40 km in 1 litre of petrol.

So for travelling 100 kilometers , $\frac{100}{13.40}=7.46$ litres of petrol is needed.

Hence, the required answer is 7.46 litres.
