How and What do I do to start?

Question

Meteorologists can determine the duration of a storm by using the function defined by T(D)=0.07 D exponent 3/2, where D is the diameter of the storm in miles and I is the time in hours. Find the duration of a storm with a diameter of 1 mile.

The duration is how many hours?

Answer 1

I assume you meant

 

T(D) = 0.07 D^3/2

 

Then

 

T(1) = 0.07 (1^3/2) hours = 0.07 hours
