Answer:
127 1/2 feet
Step-by-step explanation:
A model lighthouse uses a scale of 1/4 inch = 5 feet.
This means that 1/4 inch on the model represents 5 feet in actual life.
The height of the model lighthouse is 6 3/8 inches i.e. 51/8 inches.
The height of the actual lighthouse is:
1/4 inch = 5 feet
51/8 inches = x
Cross-multiply:
51/8 * 5 = 1/4 * x
=> x = 51/8 * 4 * 5
x = 127 1/2 feet
The height of the actual lighthouse is 127 1/2 feet.
