If AB and CD are the same distance, BC is twice the distance of either of these two, DE is triple this length. If AB is equal to 1 cm, how long is DE?

Question

In order to solve this problem, we have to create an equation that represents the relationship between the different parts of the line.
First, we read that AB and CD are the same distance. Since AB is 1 cm, this means that both AB and CD are 1 cm.
So,
AB = 1 cm       CD = 1 cm
We read that DE is triple the distance or length of either AB or CD. Since AB and CD are both 1 cm, triple (three times) that distance would be 3 cm (3 • 1cm = 3cm).
Answer: DE = 3 cm

If AB and CD Are the Same Distance, BC Is
