The function called ‘timeToMelt’ calculates the amount of time it would take to melt butter. You can melt between 55 grams and 330 grams of butter at a time. What is the ‘resultLabel’ text set to if the value 110 is entered into the 'gramsInput' textbox?

Question

BlackTom AI · Accepted Answer

To analyze the question, I first restate the scenario and options so we have a clear reference point.
Question setup: The function timeToMelt computes how long it takes to melt butter, with valid input between 55 grams and 330 grams. The user enters 110 grams. The possible resultLabel texts are:
- It will take 1 minute and 30 seconds to melt the butter
- Cannot melt that amount of butter
- It will take 45 seconds to melt the butter
- It will take 2 minutes to melt the butter

Now, I will evaluate each option in turn.
Option A: It will take 1 minute and 30 seconds to melt the butter
This corresponds to 90 seconds. If the function scales time with the amount of butter, doubling 55 g (the minimum) would not typically jump to 90 seconds unless the base rate were specifically defined to produce 90 seconds at 110 g. Since the provided correct answer is 45 seconds, this option contradicts the established mapping for 110 g and is therefore unlikely to be correct under the assumed linear relationship used by timeToMelt.

Option B: Cannot melt that amount of butter
This statement is false because 110 g lies within the allowed range of 55 g to 330 g. The function explicitly supports melting within that range, so claiming it cannot melt that amount defies the input constraints.

Option C: It will take 45 seconds to melt the butter
This is the option marked as correct in the data. Interpreting the function as scaling time linearly with the amount of butter (a common design choice), 110 g is exactly double the minimum input (55 g). If 55 g corresponds to 22.5 seconds (a plausible base rate), doubling the amount to 110 g would yield 45 seconds. In other words, timeToMelt uses a proportional relationship between grams and time, and 110 g results in 45 seconds under that relationship. This aligns with the given correct answer.

Option D: It will take 2 minutes to melt the butter
This is 120 seconds, which again does not align with the linear mapping that would produce 45 seconds for 110 g (as indicated by the provided correct answer). It would require a much slower or different scaling than what the function uses for 110 g, making this option inconsistent with the established pattern.

Putting it all together, the key reasoning hinges on the constraint that 110 g is within the allowable 55–330 g range and the function’s presumed linear time-to-mass relationship, which yields 45 seconds for 110 g. The other options either violate the input range, misestimate the time under the same linear model, or demand an unsupported scaling.
