Answer:
22.5
Step-by-step explanation:
You can set up a proportion based on the information that 5 liters of gasoline are needed for 100 kilometers
5 liters for 100 kilometers means the car uses 0.05 liters per kilometer (because 5 liters / 100 kilometers = 0.05 liters/kilometer)
Multiply the rate (0.05 liters/kilometer) by the distance (450 kilometers) 0.05liters/kilometer×450kilometers
0.05×450=22.5liters
The car will need 22.5 liters of gasoline to travel 450 kilometers
Answer:
The car will need 22.5 liters of gasoline to travel 450 kilometers.
Step-by-step explanation:
5 liters/100 kilometers = x liters/450 kilometers
5 times 450 = 100 times x
2250 = 100x
Now, solve for x.
x = 2250/100
x = 22.5
So, the car will need 22.5 liters of gasoline to travel 450 kilometers.
