This video tutorial covers the concepts of distance, speed, and time, providing formulas and examples to help students understand how to calculate each. It includes four problems: a rocket launch, a car journey, a bus trip, and a cross-country jog, each demonstrating how to apply the formulas to find average speed. The video aims to reinforce learning and correct mistakes from a recent assessment.

What is the main purpose of using formulas in this video?

• To calculate the weight of objects

• To determine the color of objects

• To find distance, time, and speed

• To measure temperature changes

In the triangle method, what does 'S' stand for?

• Strength

• Shape

• Size

• Speed

How do you calculate distance using the triangle method?

• Divide speed by time

• Multiply speed by time

• Subtract speed from time

• Add speed and time

A rocket travels 360 meters in 4 seconds. What is its average speed?

• 85 meters per second

• 95 meters per second

• 80 meters per second

• 90 meters per second

A car drives 174 miles in 3 hours. What is its average speed?

• 72 miles per hour

• 58 miles per hour

• 64 miles per hour

• 58 miles per hour

What is the average speed of a bus that travels 880 kilometers in 9 hours?

• 96.8 km/h

• 98.7 km/h

• 97.8 km/h

• 95.8 km/h

A jogger covers 14 kilometers in 2 hours. What is their average speed?

• 8 km/h

• 7 km/h

• 6 km/h

• 9 km/h

If you know the distance and speed, how do you find the time?

• Add distance and speed

• Divide distance by speed

• Subtract speed from distance

• Multiply distance by speed

What is the formula to find speed?

• Speed = Distance x Time

• Speed = Distance / Time

• Speed = Time / Distance

• Speed = Distance + Time

Why is it unnecessary to include decimal points when calculating speed?

• Decimals do not affect the calculation

• Decimals are always required

• Decimals make calculations more complex

• Decimals are only for advanced calculations
