Answer:
The distance between Lisa hand and rock is 88 inches.
<h3> Step-by-step explanation:</h3>
Consider the provided information. We need to find how far from Lisa's hand is the rock 8 seconds after it hits the surface. The rock's distance from the lake's surface changes at a rate of −2 inches per second. In 8 second the distance of rock and surface will be: Distance = 8×(2) = 16 inches below the surface of lake. We took positive 2 because distance can't be a negative number.
hope it helps you friend ☺️
