A runner is jogging on a circular track with a circumference of 400 meters. If the runner maintains a constant speed of 8 km/h, how much time will it take to complete 5 laps around the track?
Show answer & explanation
Correct answer: A
Explanation
Total distance in 5 laps = 400 × 5 = 2000 meters = 2 km
Speed = 8 km/h
Time = Distance / Speed
= 2/8 hours
= 1/4 hour
= 15 minutes
