Fuel Efficiency and Speed Calculations

The video tutorial introduces the concept of rate, focusing on speed, distance, and time. It explains how to calculate speed using the formula speed = distance/time, with examples to illustrate the process. The tutorial also covers fuel efficiency, demonstrating how to calculate the amount of fuel needed for a given distance and vice versa. The lesson concludes with a call to action for viewers to engage with the content.

What is the primary focus of the rate concept introduced in the video?

• Studying historical events

• Calculating the area of a circle

• Understanding the relationship between speed, distance, and time

• Learning about chemical reactions

If you need to reach school by 7:30 AM and the distance is 30 km, what speed should you maintain if you leave at 7:00 AM?

• 120 km/h

• 90 km/h

• 60 km/h

• 30 km/h

How do you convert 30 minutes into hours for the speed calculation?

• Add 60

• Subtract 60

• Divide by 60

• Multiply by 60

A car travels 200 km in 2 hours. What is its speed?

• 100 km/h

• 50 km/h

• 150 km/h

• 200 km/h

What is the formula used to calculate speed?

• Speed = Time x Distance

• Speed = Distance x Time

• Speed = Distance / Time

• Speed = Time / Distance

If a car can travel 10 km per liter of fuel, how much fuel is needed to travel 40 km?

• 2 liters

• 3 liters

• 4 liters

• 5 liters

What method is used to solve for unknowns in fuel calculations?

• Subtraction

• Division

• Addition

• Cross-multiplication

How many liters of fuel are needed to travel 400 km if the car's efficiency is 10 km per liter?

• 40 liters

• 30 liters

• 20 liters

• 50 liters

If you have 20 liters of fuel, how far can you travel with a car that consumes 1 liter per 10 km?

• 100 km

• 150 km

• 200 km

• 250 km

What is the relationship between fuel and distance in the context of this video?

• Fuel consumption decreases with distance

• Fuel consumption is unrelated to distance

• Fuel consumption increases with distance

• Fuel consumption remains constant regardless of distance
