Speed, Distance, and Time Problems

The video tutorial, led by science teachers, explains how to calculate speed, distance, and time using the DST triangle. It covers the importance of units in speed calculations and provides sample problems to demonstrate how to find each variable. The tutorial concludes with a review of the DST triangle method.

What two terms are used interchangeably when discussing how fast an object is moving?

• Speed and velocity

• Speed and rate

• Rate and velocity

• Distance and time

Why is it important to include units when calculating speed?

• Units help in converting measurements

• Units are not important

• Units ensure the accuracy of the calculation

• Units differentiate between different types of speed

What does the DST triangle help you calculate?

• Only speed

• Only distance

• Speed, distance, and time

• Only time

If you want to find the speed using the DST triangle, which formula would you use?

• Speed = Distance x Time

• Speed = Time / Distance

• Speed = Distance + Time

• Speed = Distance / Time

In the sample problem, what was Lance Armstrong's speed during his bike ride?

• 15 miles per hour

• 18 miles per hour

• 17 miles per hour

• 16 miles per hour

What was the total distance Andrew traveled from Las Vegas to Riverside?

• 250 miles

• 280 miles

• 300 miles

• 270 miles

What was Andrew's constant speed during his trip?

• 90 miles per hour

• 80 miles per hour

• 85 miles per hour

• 95 miles per hour

How long will it take Robin to reach Disneyland if she travels at 65 miles per hour?

• 7.0 hours

• 6.5 hours

• 6.2 hours

• 5.5 hours

What formula would you use to find time using the DST triangle?

• Time = Distance x Speed

• Time = Speed / Distance

• Time = Distance / Speed

• Time = Speed x Distance

What is the easiest way to solve speed, distance, and time problems according to the video?

• Using a calculator

• Using the DST triangle

• Guessing the answers

• Memorizing formulas
