To find the difference in elevation between the top of the apple tree and the tips of its roots, we need to add the height of the tree to the depth of its roots, as follows:
- The height of the apple tree is 3.6 feet.
- The roots extend 1.75 feet below ground.
Now, we calculate the total difference in elevation:
\[ \text{Total elevation difference} = \text{Height of tree} + \text{Depth of roots} = 3.6 \text{ feet} + 1.75 \text{ feet} \]
\[ 3.6 + 1.75 = 5.35 \text{ feet} \]
Now, since the answer choices are in meters, we need to convert 5.35 feet to meters. To do this, we can use the conversion factor \(1 \text{ foot} \approx 0.3048 \text{ meters}\):
\[ 5.35 \text{ feet} \times 0.3048 \text{ meters/foot} \approx 1.63008 \text{ meters} \]
It seems that the options provided are significantly higher than this. Let's calculate again the values based on the difference:
The absolute difference in elevation (top of the tree to the tip of the roots) is:
\[ 3.6 \text{ feet } (above ground) + 1.75 \text{ feet } (below ground) = 5.35 \text{ feet} \]
Since the provided answer options are all in meters, we'll provide the previously mentioned conversion to find what that difference in elevation would be if it were needed in terms of meters, observing possible alternative interpretations.
\[ 5.35 \text{ feet} = \frac{5.35}{3.281} \text{ meters}; (as;another;way;to;convert;rather;than;using; foot;to;meter;and;reassessing) \]
If the options are fixed as presented in meters, none of these would apply within the typical conversions or context for roots and trees, hence we would verify these answers cannot necessarily exist over standard conversions or a misunderstanding of measurement or typographical error in the choice list.
For the options A-D presented, none match based on a simple calculation in these defined roots and would presumingly readjust with context as needed.
The answer is thus revealed logically as:
5.35 feet (not present in the options above).
I apologize for any confusion with the answer options. Please double-check the problem statement or data choice for a possible translify in conversion values or operational measures if needing to reach the supposed options in a calculation re-check!
