Answer:
Yes, it is a sensible estimate
Explanation:
To answer this, I will assume that there are no further details. So, my explanation will be based on a general assumption
From the floor to the top of a kitchen counter, the average height is 0.91 meters (36 inches)
Using Sharon's estimate, from the kitchen counter to the ceiling will be 1.09 meters (2 - 0.91)
This implies that the kitchen counter is closer to the floor than the ceiling.
Hence, the estimate is sensible
