Answer:
T = 1 + 1.5x
Explanation:
Based on the information provided and we can subtract the time and rain gauge at the end of the data with the time and rain gauge at the beginning. This tells us that in 4 hours the rain increased by 6 inches. If we divide these two values we get.
6 inches / 4 hours = 1.5 inches per hour
We now see that rain has been accumulating at a rate of 1.5 inches per hour. We can use this info to create a linear model where we multiply this rate by the number of hours that have passed (x) after 1 hour which would give us the total amount of rain (T)
T = 1 + 1.5x
