Answer:
The estimated taken to drive downtown using App is 38.4 minutes
Step-by-step explanation:
Given as :
The initial time taken to drive downtown = i = 48 minutes
The percentage error of time = r = 20%
Let The estimated time using app = t min
Let the time = 1 min
<u>Now, according to question</u>
The estimated time using app = The initial time taken to drive downtown ×
Or, t minutes = i minutes ×
Or, t = 48 minutes ×
Or, t = 48 minutes ×
Or, t = 48 minutes ×
∴ t = minutes
I.e t = 38.4 minutes
Or, The estimated time using app = t = 38.4 min
Hence, The estimated taken to drive downtown using App is 38.4 minutes Answer
