On a trip you travel 308km in 3.5h and use 32L of gasoline.

A) What is your average speed in km per hour?
B)What is your gas mileage in miles per gallon?

To find the average speed in km per hour, you can divide the total distance traveled by the total time taken.

A) Average speed = Total distance / Total time

In this case, the total distance traveled is 308 km and the total time taken is 3.5 hours. Therefore,

Average speed = 308 km / 3.5 hours

To find the gas mileage in miles per gallon, you need to convert the distance traveled from kilometers to miles and the amount of gasoline used from liters to gallons.

To convert kilometers to miles, you can use the conversion factor of 1 km = 0.621371 miles.
So, 308 km is equal to 308 * 0.621371 miles.

To convert liters to gallons, you can use the conversion factor of 1 liter = 0.264172 gallons.
So, 32 liters is equal to 32 * 0.264172 gallons.

B) Gas mileage = Distance in miles / Gasoline in gallons

In this case, the distance is 308 km * 0.621371 miles per km (converted distance) and the gasoline used is 32 * 0.264172 gallons (converted gasoline). Therefore,

Gas mileage = (308 km * 0.621371 miles per km) / (32 * 0.264172 gallons)

Now, you can use a calculator to solve these equations.

A) Average speed = 308 km / 3.5 hours
= 88 km/h

B) Gas mileage = (308 km * 0.621371 miles per km) / (32 * 0.264172 gallons)
≈ 14.4 miles/gallon
