A whale is swimming at a current depth of 15 meters below the surface. It swims up toward the surface and arrives there 9.5 seconds later. Find the quotient that best describes the rate of change in the whale’s depth. Give your answer to the nearest hundredth.(1 point)
The quotient that best represents the rate of change in the whale’s depth is meters/second.
1.58
rate of change is (change in depth)/(change in time)
= -15/9.5 = ____ m/s
what is it
Solve using division of rational numbers. If a car’s value decreases by $2,500 in the first 6 months, how much does the value decrease per month? (Round to the nearest hundredth.) (1 point)
To find the quotient that represents the rate of change in the whale's depth, we need to determine the difference in depth and the time taken.
The initial depth of the whale is 15 meters below the surface.
The final depth of the whale is at the surface, which is 0 meters.
The time taken for the whale to swim up to the surface is 9.5 seconds.
To find the rate of change, we divide the difference in depth by the time taken:
Rate of change = (Final depth - Initial depth) / Time taken
Rate of change = (0 - (-15)) / 9.5
Rate of change = 15 / 9.5
Rate of change ≈ 1.58 meters/second (rounded to the nearest hundredth)
Therefore, the quotient that best represents the rate of change in the whale's depth is 1.58 meters/second.
