Answer

Answer:

17

Explanation:

Step1: Identify overlapping time segments

First, find when Lynn's speed line is above Kael's:

  1. 0 to 12 minutes: Lynn's speed > Kael's
  2. 20 to 28 minutes: Lynn's speed > Kael's

Step2: Calculate duration of first segment

Subtract start from end time: $12 - 0 = 12$ minutes

Step3: Calculate duration of second segment

Subtract start from end time: $28 - 20 = 5$ minutes

Step4: Sum the two durations

Add the two time periods together: $12 + 5 = 17$ minutes
