Answer:
Average speed of the two boats are 28 km/hr. and 24 km/hr.
Step-by-step explanation:
Let the average speed of the boat with larger speed is x km/h and that of the other boat is y km/h.
Now, given that x - y = 4 ...... (1)
If the distance, that the first boat covers in 3 hrs. is d km then the second boat covers d km in 3.5 hrs.
Therefore, and
Now, from equation (1), we can get
⇒
⇒ km/hr.
Again, km/hr.
Therefore, the average speed of the two boats is 28 km/hr. and 24 km/hr. (Answer)

From this, we can see that the largest negative numbers will be the least amount of rain and the largest positive numbers will be the greatest amount of rain.
This means that the order would be :
And in years this would be :
