How to Calculate Speed and Velocity

This video tutorial covers the concepts of speed and velocity, explaining the difference between the two and how to calculate them using a triangle method. It provides examples of calculating speed, velocity, time, and distance, using real-world scenarios such as a runner, a car, and a school bus. The tutorial emphasizes the importance of understanding the direction in velocity calculations and offers a practical approach to solving problems using the speed triangle.

What is the formula for calculating speed?

• Speed equals time minus distance

• Speed equals distance times time

• Speed equals distance divided by time

• Speed equals time divided by distance

In the triangle method, what operation do you perform to find time?

• Multiply speed and distance

• Divide distance by speed

• Subtract speed from distance

• Add speed and distance

A student runs 250 meters in 30 seconds. What is her speed?

• 10 meters per second

• 9.5 meters per second

• 8.33 meters per second

• 7.5 meters per second

A car travels 75 kilometers north in 1.5 hours. What is its velocity?

• 25 kilometers per hour

• 100 kilometers per hour

• 75 kilometers per hour

• 50 kilometers per hour

How far does a car travel if it moves at 50 mph for 4.5 hours?

• 225 miles

• 275 miles

• 250 miles

• 200 miles
