It takes 48 minutes to drive downtown. An app estimated that it would be less than that. If the error was 20%, what was the app's estimate?

Answer:

The app's estimated time is 38.4 minutes

Explanation:

According to the question, it took 48 minutes to drive downtown because the app estimated it would take less time, and the error was 20%.

So the app's estimate is 48*(1-20%) 

=48*80% 

=48*0.8(digital multiplication) 

=38.4 minutes.

Therefore, the app's estimate is 38.4 minutes
