To describe violent storms, such as hurricanes and tornadoes, meteorologists use the formula D^3=830t^2, where D is the diameter (in km) of the storm and t is the time (in h) that the storm is expected to last. If a storm has a diameter of 25km , how long is it expected to last?

take 25^3 and divide it by 830 then take the square root of that
