Question

The first measurements of the sea depth was made in 1840 in the centra south of Atlantic, where a plummet was lowered 2425 fathoms. What is the depth in meters? Note 1 fathom=6ft, 1ft=12in, 1ft=2.54*10

Answer 1

Answer:

4435 m  

Explanation:

1. Number of feet

$\text{No. of feet} = \text{2425 fathoms} \times \dfrac{\text{6 ft}}{\text{1 fathom}} = \text{14 550 ft}$

2. Number of inches  

$\text{No. of inches} = \text{14 550 ft} \times \dfrac{\text{12 in}}{\text{1 ft}} =\text{174 600 in}$

3. No. of centimetres

$\text{No. of centimetres} = \text{174 600 in} \times \dfrac{\text{1 cm}}{\text{2.54 in}} = \text{443 500 cm}$

4. No. of metres

$\text{No. of metres} = \text{443 500 cm} \times \dfrac{\text{1 m}}{\text{100 cm}} = \textbf{4435 m}$
