It's raining outside, and after 1 hour of rain, the water level in Jake's pond is 2 meters. After 3 hours, the water level is 2.

Answer: 0.4 meters per hour.

Step-by-step explanation:

The rate of change of distance with respect to time is known as speed.

Formula : $\text{Rate of change}=\dfrac{\text{Change in position}}{\text{Change in time}}$

Given : It's raining outside, and after 1 hour of rain, the water level in Jake's pond is 2 meters. After 3 hours, the water level is 2.8 meters.

i.e. Change in position= 2.8-2=0.8 meters

Change in time = 3-1=2 hours

i.e. $\text{Rate of change}=\dfrac{0.8}{2}=0.4$

Hence, the rate of change =0.4 meters per hour.
