Question

Answer 1

Given: Eratosthenes was in about 274 BC. Sir Isaac Newton was born in 1642 AD.

Required: To determine the difference between both dates.

Step-by-step explanation: The AD starts right after BC ends. There is no year zero. So we need to count from 247 BC to 1 BC and then 1 AD to 1642 AD.

Thus the difference between the birth dates of Eratosthenes and Sir Isaac Newton is-

`\begin{gathered} =247+1642 \\ =1889\text{ years} \end{gathered}`

Final Answer: 1889 years.
