Explanation:

Information we need

• Jayden runs 3 laps in 5 minutes

Solving

• Time taken by Jayden to run 2/5 kilometers (1 lap) = 5/3 minutes
• Time taken to run 1 km = Time taken to run 2/5 km x 5/2
• Time taken to run 1 km = 5/3 x 5/2
• ⇒ 25/6 minutes (improper fraction form)
• ⇒ 4 1/6 minutes (mixed number form)
• ⇒ 4.17 minutes (decimal form)
