Answer:
A. 2,121 years
Explanation:
This question can be looked at as a speed and distance question where 3.3 mm/yr is the speed and 7 m is the distance. So as the formula normally goes;
time = distance/speed
= [tex]\frac{7 m}{3.3mm/yr} =\frac{7m}{0.0033m/yr} = 2121 years[/tex]
Please note that it was important to change the rate of rising of the sea from mm/year to m/year because the distance was in metres
The total tome it will take the sea to rise 7 m with the current rate of rising the sea level is 2121 years.
The speed of a body is the rate at which it covers the total distance is in the time taken. The speed of the body is given as,
[tex]s=\dfrac{d}{t}[/tex]
Here, (d) is the distance travelled by the body and (t) is time taken by the body to cover that distance.
Sea level is currently rising at 3.3 mm/yr, and scientists predict that global warming could cause a rise in sea level of 7 m if left unabated.
Thus put the value of the rate of the rising and the total sea level in the above formula of speed as,
[tex]3.3=\dfrac{7}{t}\\t=2121\rm \; years[/tex]
Hence, the total tome it will take the sea to rise 7 m with the current rate of rising the sea level is 2121 years.
