ABC is a straight line. The length of BC is three times the length of AB.
AC = 80 metres.
Work out the length BC.

AB = 20 metres

BC = 60 metres

Step-by-step explanation:

Let AB = x

Then, BC = 3x

Condition:

=> x+3x = 80

=> 4x = 80

Dividing both sides by 4

=> x = 20

So,

AB = 20 metres

BC = 3(20)

BC = 60 metres
