Solution:
This task can be solved using two methods. Let’s consider each of them.
Method 1.
AC: BC = 2: 5.
As you can see, the length of the BC is 5/2 = 2.5 times that of the AC.
BC = 2.5 * AC.
BC = 2.5 * 14 = 35 cm.
Answer: 35 cm.
Method 2.
AC: BC = 2: 5.
That is, the speaker consists of 2 parts, 14 cm long.It means that 1 part is equal to 7 cm.
The sun consists of 5 parts. Let’s find the length of the BC.
BC = 5 * 7 = 35 cm.
Answer: 35 cm.
