Question

A parasail is $\frac{3}{100}$

mile above the water. After 5 minutes, the parasail is $\frac{1}{50}$
mile above the water. Find the change in height of the parasail.
The change is height is
mile.

Answer 1

The parasail starts 3/100 mile above the water, then falls to 1/50 mile, or 2/100 mile. 3-2=1, so it fell 1/100 mile. Since it fell, the change would be negative.

The change in height is -1/100
