1. Calculate the difference in height between the current height and the past height:
254.7 - 245 = 9.7 \, \text{mm}
2. Divide the difference in height by the growth rate to find the number of years ago:
9.7 \, \text{mm} / 0.2 \, \text{mm/year} = 48.5 \, \text{years}
3. The stalagmite was 245 mm tall 48.5 years ago.
The answer is 48.5 years.
