Respuesta :
The difference in water level will be calculated using the relation : (11.16-x) mm
Given that :
Rate at which water is rising = 1.8mm/year
Time period = 6.2 years
At the rate given :
Average water level at the period, time = 6.2 years
Average water level = Rate of change × time
Average water level = 1.8 × 6.2 = 11.16 mm
To obtain the difference in average water level and a certain measured point :
The value of water level in the measured point isn't given; assume this value is x
Hence, difference between average water level and point, x
Difference = (11.16 - x) mm
