Answer 1

Answer:

Kindly check explanation

Step-by-step explanation:

Given the following :

Let absolute variation in the wait time at the bus stop = v

Variation = ±3 minutes

Average bus run through the city = 15 minutes

Hence, the minimum and maximum run values due to the variation can be modeled as:

|variation - average run| = ±3

|v - 15| = ±3

minimum : v = - 3 +. 15 = 12 minutes

Maximum : v = 3 + 15 = 18 minutes
