A runner completes 5(1/3) laps of a 400-meter track. Each lap takes 1.6 minutes. How many kilometres does the runner cover, and what is the total time taken?
Show answer & explanation
Correct answer: D
Explanation
Given:
Track length = 400 meters
Laps completed = 5(1/3)
= 16/3 laps
Total distance = 400 × 16/3
= 6400/3 meters
= 2133.33 meters
= 2.13 km
Time per lap = 1.6 minutes
Total time = 16/3 × 1.6
= 25.6/3 minutes
= 8.5 minutes
