Question 115260: 6. Construction
The building ciode in a certain county requires that public buildings be able to withstand a wind pressure of 25 lb/ft^2. The pressure P is related to the wind speed v in miles per hour by the formula P = v^2/390. What wjind speed will produce the maximum pressure allowed? Round to two significant digits.

The relation between pressure(P) and wind speed(v) is P = v^2 / 390.
The maximum pressure allowed is 25 lb/ft^2.
Let V be the wind speed which creates maximum pressure.
Then, 25 = V^2 / 390.
That is, V^2 = 9750
Or, V = 98.74 miles/hour.
