Mastering Speed, Distance, and Time with Real Life Applications

This video tutorial from Xcelerate Maths introduces the DST triangle to explain the relationship between speed, distance, and time. It covers the rules for calculating each of these variables and provides practical examples, including a car journey, an express train, a snail's pace, and a rocket to the moon. The tutorial concludes with challenge questions to test understanding.

What does the DST triangle help you remember?

• The order of operations

• The rules for calculating speed, distance, and time

• The formula for area of a triangle

• The steps for solving quadratic equations

What is the formula for calculating speed using the DST triangle?

• Speed = Time / Distance

• Speed = Distance x Time

• Speed = Time x Distance

• Speed = Distance / Time

What is the formula for calculating time using the DST triangle?

• Time = Distance x Speed

• Time = Speed / Distance

• Time = Distance / Speed

• Time = Speed x Distance

What is the formula for calculating distance using the DST triangle?

• Distance = Time / Speed

• Distance = Speed / Time

• Distance = Speed x Time

• Distance = Time x Speed

• 9 seconds

• 8 seconds

• 7 seconds

• 6 seconds

A snake can strike in 0.2 seconds from 3 meters away. What is its speed?

• 10 m/s
