To determine how much higher the deepest point in the Channel Tunnel is compared to the deepest point in the Eurasia Tunnel, we need to compare their depths below sea level.
- Depth of the Channel Tunnel: -250 feet (below sea level)
- Depth of the Eurasia Tunnel: -348 feet (below sea level)
To find out how much higher the Channel Tunnel is, we can calculate the difference in their depths:
\[
\text{Difference} = \text{Depth of Eurasia Tunnel} - \text{Depth of Channel Tunnel}
\]
\[
\text{Difference} = (-250) - (-348)
\]
This simplifies to:
\[
\text{Difference} = -250 + 348
\]
\[
\text{Difference} = 98 , \text{feet}
\]
Therefore, the deepest point in the Channel Tunnel is 98 feet higher than the deepest point in the Eurasia Tunnel.
