Using the following numbers for your calculations, how much weight will come off your drive axles?

Miles per gallon: 6

Miles travelled: 360

Percentage of fuel weight on drive axles: 30%

Miles travelled: 360

Percentage of fuel weight on drive axles: 30%

- 200 pounds
- 210 pounds
- 300 pounds
- 144 pounds

#### Quote From The CDL Manual:

To calculate the percentage of a value, you simply multiply the total value times the percentage you're looking for, and then divide by 100.

#### TruckingTruth's Advice:

If you're getting 6 miles per gallon and you travel 360 miles:

360/6 = 60 gallons of fuel

60 gallons x 8 pounds per gallon = 480 pounds of total fuel burned off

Since 30% of the weight of fuel goes on our drive axles, we need to know what 30% of 480 is:

30 x 480 / 100 = 144 pounds coming off the drive axles

360/6 = 60 gallons of fuel

60 gallons x 8 pounds per gallon = 480 pounds of total fuel burned off

Since 30% of the weight of fuel goes on our drive axles, we need to know what 30% of 480 is:

30 x 480 / 100 = 144 pounds coming off the drive axles

Using 6 miles per gallon as your fuel mileage and 8 pounds per gallon for the weight of fuel, how much total fuel weight will you burn off in 600 miles?

- 480 pounds of fuel
- 850 pounds of fuel
- 600 pounds of fuel
- 800 pounds of fuel

#### Quote From The CDL Manual:

To figure out how many gallons of fuel you'll burn off, simply divide the number of miles travelled by the miles per gallon

Number of miles travelled / miles per gallon = gallons of fuel burned off

Number of miles travelled / miles per gallon = gallons of fuel burned off

#### TruckingTruth's Advice:

600 miles travelled / 6 miles per gallon = 100 gallons of fuel burned off

100 gallons x 8 pounds per gallon = 800 pounds of fuel burned off

100 gallons x 8 pounds per gallon = 800 pounds of fuel burned off

Using 7 miles per gallon as your fuel mileage and 8 pounds per gallon for the weight of fuel, how much total fuel weight will you burn off in 210 miles?

- 240 pounds
- 270 pounds
- 210 pounds
- 180 pounds

#### Quote From The CDL Manual:

To figure out how many gallons of fuel you'll burn off, simply divide the number of miles travelled by the miles per gallon

Number of miles travelled / miles per gallon = gallons of fuel burned off

Number of miles travelled / miles per gallon = gallons of fuel burned off

#### TruckingTruth's Advice:

210 miles travelled / 7 miles per gallon = 30 gallons of fuel burned off

30 gallons x 8 pounds per gallon = 240 pounds of fuel burned off

30 gallons x 8 pounds per gallon = 240 pounds of fuel burned off

Using the following numbers for your calculations, how much weight will come off your steer axle?

Miles per gallon: 7

Miles travelled: 280

Percenatage of fuel weight on steer axle: 80%

Miles travelled: 280

Percenatage of fuel weight on steer axle: 80%

- 310 pounds
- 280 pounds
- 300 pounds
- 256 pounds

#### TruckingTruth's Advice:

If you're getting 7 miles per gallon and you travel 280 miles:

280/7 = 40 gallons of fuel

40 gallons x 8 pounds per gallon = 320 pounds of total fuel burned off

Since 80% of the weight of fuel goes on our steer axle, we need to know what 80% of 320 is:

80 x 320 / 100 = 256 pounds coming off the steer axle

280/7 = 40 gallons of fuel

40 gallons x 8 pounds per gallon = 320 pounds of total fuel burned off

Since 80% of the weight of fuel goes on our steer axle, we need to know what 80% of 320 is:

80 x 320 / 100 = 256 pounds coming off the steer axle
