Mr. Bradford is filling up a pool with water. The depth of water in the pool can be represented by the function d(t)=0.25t+30, where t is the time in minutes and d(t) is the depth, in inches, of water in the pool.

How deep is the water in the pool when MR. Bradford starts filling the pool with water?

During a recent rain shower, Zachary found that the relationship between the depth of water in his pool and the time it was raining was linear.

The function d(t) = 2t + 30 represents this relationship, where t is the time, in hours, since it started raining and d(t) is the depth, in centimeters, of water in the pool.

How many centimeters is the depth of water in the pool increasing for every additional hour that it rains?
