Answer 1

Answer:

Step-by-step explanation:

48 x .20 = 9.6

48- 9.6 = 38.4

Answer 2

The estimate given by the app was 38.4 minutes. Of the answer choices provided, this is the closest option to the estimate, so the correct answer is "38.4 minutes".

If the error was 20%, the estimate was 80% of the actual time. We can represent the actual time as 100% and the estimate as 80% of that time. To find the estimate, we multiply the actual time by 80%:

Estimate = 80% * Actual time = 80% * 48 minutes

To calculate the estimate, we convert the percentage to a decimal and multiply it by the actual time:

Estimate = 0.80 * 48 minutes = 38.4 minutes

It is important to keep in mind that the estimate given by an app or any other source may not always be accurate, and it's always a good idea to allow for some extra time in case of unexpected traffic, detours, or other delays.
