Answer
Thabo took 14 minutes and 44 seconds longer than Sibusiso.
Solution
To find out how much longer Thabo took than Sibusiso, we subtract Sibusiso’s time from Thabo’s time.
Sibusiso’s time: 1:52:27
Thabo’s time: 2:07:11
Step 1: Convert both times to seconds.
• Sibusiso’s time in seconds = (1 × 3600) + (52 × 60) + 27 = 3600 + 3120 + 27 = 6747 seconds
• Thabo’s time in seconds = (2 × 3600) + (7 × 60) + 11 = 7200 + 420 + 11 = 7631 seconds
Step 2: Find the difference in seconds.
• Difference = 7631 seconds – 6747 seconds = 884 seconds
Step 3: Convert 884 seconds back to minutes and seconds.
• Minutes = 884 ÷ 60 = 14 minutes with a remainder
• Seconds = 884 – (14 × 60) = 884 – 840 = 44 seconds
Therefore, Thabo took 14 minutes and 44 seconds longer than Sibusiso.

The Deep Dive
Thabo took 14 minutes and 44 seconds longer than Sibusiso. To find this, subtract Sibusiso's time from Thabo's time: Thabo's time: 2:07:11 Sibusiso's time: 1:52:27 Now, let's break it down: - Minutes: 07 - 52 = 15 (We need to borrow 1 from the hours, making it 1 hour = 60 minutes + 7 = 67 minutes) - Seconds: 11 - 27 = -16 (So we borrow another minute, making it 60 seconds + 11 = 71 seconds) Now convert properly: - Minutes: 66 - 52 = 14 - Seconds: 71 - 27 = 44 So the total difference is 14 minutes and 44 seconds.
