How fast must velma move in order for her 10 ice cream cone to melt in 30 minutes as measured by mort?

To determine how fast Velma must move for her 10 ice cream cones to melt in 30 minutes, we need to consider factors like temperature, sunlight, and the specific melting rate of the ice cream. Assuming a constant melting rate, she would need to maintain a speed that minimizes exposure to these conditions, perhaps by staying in the shade or moving quickly enough to reduce melting. Without specific data on these factors, it's impossible to calculate an exact speed, but the key is to balance movement with environmental conditions.
