If you multiple the numbers together...you will get the answer....480 pounds of water in total
If you represent the problem in a diagram, you will form a triangle with 3 known length of the sides. When you are given all sides, and you are asked to find an angle, you can use the cosine law.
b^2 = a^2 + c^2 - 2ac*cosB
1.4^2 = 1.9^2 + 1^2 - 2(1.9*1)(cosB)
B = 45.78°
3.25×5=16.25
5 hours for 1 person
16.25×2=32.5
5 hours for 2 people
To find this we need to subtract July rainfall (8.35) and Octobers rainfall (3.87) which equals 4.48.
