Unit Conversion and Speed Problems

The video tutorial covers calculations for speed and velocity, focusing on converting time units from minutes to hours and calculating average speed. It includes examples such as a car traveling a certain distance and Usain Bolt's running speed, demonstrating how to convert units and apply formulas to find speed in km/h.

What is the first step when solving a speed problem with different units?

• Ignore the units and solve the problem.

• Convert all given units to the desired units.

• Calculate the speed directly.

• Use a speed triangle immediately.

How do you convert 360 minutes into hours?

• Multiply by 60.

• Divide by 60.

• Add 60.

• Subtract 60.

What is the average speed of a car that travels 300 kilometers in 6 hours?

• 30 km/h

• 60 km/h

• 50 km/h

• 40 km/h

What is the purpose of the speed triangle in solving problems?

• To find the direction of travel.

• To convert units.

• To calculate distance only.

• To visualize the relationship between speed, distance, and time.

How do you convert miles to kilometers?

• Add 1.609.

• Multiply by 1.609.

• Divide by 1.609.

• Subtract 1.609.

What is Usain Bolt's speed if he runs 70 miles in 2.5 hours?

• 50 km/h

• 45 km/h

• 60 km/h

• 28 km/h

What is the conversion factor from miles to kilometers?

• 1 mile = 1.609 km

• 1 mile = 1.5 km

• 1 mile = 2 km

• 1 mile = 1.2 km

What should you do if you are converting from a larger unit to a smaller unit?

• Subtract the smaller unit from the larger unit.

• Add the two units together.

• Multiply the larger unit by the smaller unit.

• Divide the larger unit by the smaller unit.

What is the key takeaway from the lesson on speed and velocity?

• Convert units before solving.

• Ignore unit conversions.

• Use only one method for all problems.

• Always calculate speed first.

What is the correct approach when converting from a smaller unit to a larger unit?

• Divide the smaller unit by the larger unit.

• Multiply the smaller unit by the larger unit.

• Add the two units together.

• Subtract the larger unit from the smaller unit.
