Solution Summary
The solution shows how to set up and solve system of linear equations to find out how long the two rainstorms lasted.
Solution Preview
x: the length of the first storm (in hours); y: the length of the second storm (in hours)
Rain fell that week for a total of 70 hours, so
x + y = 70
volume of the storm = rate ...
