Question

The bus routes in a city run on average every 15 minutes. The route times can vary by three minutes. Which absolute value equation can be used to find the maximum and minimum wait times at a bus stop?

Answer 1

Answer:

$Max = 18\ mins$

$Min = 12\ mins$

Step-by-step explanation:

Given

$Time = 15\ mins$

$Variation = 3\ mins$

Required

Determine the max and min values

The max value is calculated as thus:

$Max = Time + Variation$

$Max = 15\ mins + 3\ mins$

$Max = 18\ mins$

The min value is calculated as thus:

$Min = Time - Variation$

$Min = 15\ mins - 3\ mins$

$Min = 12\ mins$
