Two rainstorms occurred in one week in a certain area.?

Question

Two rainstorms occurred in one week in a certain area. The first storm lasted 35 hours, and the second storm lasted 20 hours, for a total 1225 ml of rain. What was the rate of rainfall for each of the two storms if the sum of the two rates was per hour?

first strom ML/HR

second strom ML/HR

Answer 1

oh for fxck's sake..i'm not about to do some maths..i mean come on it's the school holidays.

Answer 2

The equation to get the rainfall amounts for each storm would be:

20x+35x=1225

Add 20 and 35 which would be 55x

So now it's 55x=1225

divide 55 on both sides

so x=22.2727

Now multiply it by the number of hours each storm lasted so

35(22.2727)=779.5445

So in the first storm produced 779.5445mL of rain

Do the same for the second storm

20(22.2727)=445.454mL of rain.

Now divide the rainfall amount by the hours it lasted to get the rainfall rate:

First storm: 445.454/20= 22.2727mL/hour

Second storm 779.5445/35=22.2727 mL/hour
