A car travels 50km in 4 liters. How far will it go by 20 liters of petrol?
50km/4Liters = 12.5 km/Liter.
d = 12.5km/Liter * 20Liters =
Well, you used 5 times as much fuel.
Shouldn't you have gone 5 times as far?
To find out how far the car will go with 20 liters of petrol, we can use the concept of ratios.
Given:
1 liter of petrol allows the car to travel 50 km.
So the ratio of petrol to distance traveled is:
4 liters : 50 km
To find out how far the car will go with 20 liters of petrol, we need to set up a proportion and solve for the unknown distance.
Using the proportion:
4 liters / 50 km = 20 liters / x km
Cross-multiplying, we get:
4 * x = 50 * 20
Simplifying further,
4x = 1000
Dividing by 4,
x = 250 km
Therefore, with 20 liters of petrol, the car will travel a distance of 250 km.
To find out how far the car will go with 20 liters of petrol, you need to determine the car's fuel efficiency, which is the distance traveled per liter of petrol.
Given that the car travels 50 km in 4 liters, you can calculate its fuel efficiency by dividing the distance traveled by the amount of petrol used:
Fuel Efficiency = Distance Traveled / Petrol Used
Fuel Efficiency = 50 km / 4 liters
Simplifying, the car's fuel efficiency is 12.5 km/liter.
Now, to calculate the distance the car will go with 20 liters of petrol, you can multiply the fuel efficiency by the amount of petrol:
Distance = Fuel Efficiency * Petrol
Distance = 12.5 km/liter * 20 liters
The distance the car will go with 20 liters of petrol is 250 kilometers.
