Question

During a thunder storm, the amount of rain on the ground increased at an average rate of 0.25 inch per hour. There was already 4.5 inches of rain on the ground when the storm started. Write an equation that can be used to determine the total amount of rain on the ground (T), in inches, after h hours of the storm.

Answer 1

4.5 + 0.25T

Explanation: 4.5 inches of rain already exist on the ground and 0.25 inches are being added every hour. And since the amount of hours are “T”, the amount of rain after T hours will be 0.25T
