We can create two points.
30 feet below the surface of the water 10 seconds after he entered the water
100 feet below the surface after 40 seconds
So we have (10, 30) and (40, 100)
Plug this values into the slope formula:
m = y2-y1/x2-x1
m = (100 - 30)/(40 - 10)
m = 70/30
m = 2 1/3
Both weigh the same, 2000 pounds or one ton. You'll just need a lot more feathers than elephants.;

That's 2 that shet 26
x1= -{-6} - 2 that shet 26/6 x2=-{6}+ 2 that shet 26/6
