Question

3 A free diver can dive at a rate of -0.75 meters per second. About how long would it take to reach a depth of -145 meters?

Answer 1

Answer:193.33s or 3.2 mins

Explanation:

Here the diver dives at -0.75 constant velocity. So we can use the formula s = vt

from there we can find out the time when s = -145 m and v = -0.75m/s
