Isolating S:
B = [(S+Z)/4]·h
B/h = (S + Z)/4
<h2>S = (4B/h) - Z</h2>
Let umber of hours in which snowfalls of the both towns become equal = x
Given that rate at which snow depth is increasing in town 1 =
inches per hour
Then amount of snow fall in x hours in twon 1 =
Given that rate at which snow depth is increasing in town 2 =
inches per hour
Then amount of snow fall in x hours in twon 2 =
when snow fall becomes equal then we get equation:
0=x
Hence final answer is 0 hours.
