Answer: The ice sheet's thickness decrease every 6 weeks= 1.5 meters
Step-by-step explanation:
GIven: At the beginning of spring, the ice starts to melt. The variable sss models the ice sheet's thickness (in meters) t weeks after the beginning of spring.
At t=0,
So, Thickness of ice sheet at the beginning = 4 meters
Now at t= 6, we get
Thickness of ice sheet after 6 weeks = 2.5 meters
Decrease in thickness = 4 meters - 2.5 meters = 1.5 meters
Hence, the ice sheet's thickness decrease every 6 weeks= 1.5 meters
Answer:
70°f is the median temperature of the pond
t - time, d - distance, v - speed
Let x be Jaime's normal rowing speed.
The wind adds 2 miles per hour to her speed when she is rowing with the wind - so her speed is x+2, and she can row 60 miles at that speed in time t.
The wind subtracts 2 miles per hour from her speed when she is rowing against the wind - so her speed is x-2, and she can row 48 miles at that speed in the same time t.
Set the expressions for t equal to each other:
Jaime's normal rowing speed is 18 miles per hour.
