A car engine burns gasoline at the rate of two gallons per hour. If it does this for 8 hours each day, approximately how many weeks will it take for the car to burn 11,200 gallons of gasoline?
So it burns 16 gallons/day
Number of days = 11200/16 or 725
This morning, Leila's car had 19.85 gallons of fuel. Now,4.9 gallons are left. How much fuel did Leila use?
To calculate the number of weeks it will take for the car to burn 11,200 gallons of gasoline, we need to determine the total number of hours required.
Given that the car burns gasoline at a rate of 2 gallons per hour, we can calculate the total number of gallons burned in 8 hours using the formula:
Gasoline burned in 8 hours = Rate of burning * Number of hours
= 2 gallons/hour * 8 hours
= 16 gallons
So, the car burns 16 gallons of gasoline in 8 hours.
To find the number of weeks it will take to burn 11,200 gallons of gasoline, we divide the total number of gallons by the number of gallons burned in 8 hours:
Number of weeks = Total number of gallons / Gasoline burned in 8 hours
= 11,200 gallons / 16 gallons
= 700 weeks
Therefore, it will take approximately 700 weeks for the car to burn 11,200 gallons of gasoline.
To find out how many weeks it will take for the car to burn 11,200 gallons of gasoline, we need to calculate the total hours it will take and then convert that to weeks.
First, let's find the total number of hours it will take the car to burn 11,200 gallons of gasoline. Given that the engine burns gasoline at a rate of two gallons per hour, we can set up a proportion:
2 gallons / 1 hour = 11,200 gallons / x hours
Multiplying both sides by x and dividing by 2, we get:
x = (11,200 gallons) / (2 gallons/hour)
x = 5,600 hours
Now, let's convert 5,600 hours to weeks. Assuming there are 7 days in a week and 24 hours in a day:
1 week = 7 days
1 day = 24 hours
So, we can set up another proportion:
7 days / 1 week = 24 hours / x hours
Multiplying both sides by x and dividing by 7, we get:
x = (24 hours) / (7 days/week)
x = 3.43 weeks (rounded to two decimal places)
Therefore, it will take approximately 3.43 weeks for the car to burn 11,200 gallons of gasoline.
