Answer:
10 minutes and 24 seconds
Step-by-step explanation:
the total perimeter of the rectangle = 260m
2 round of the field = 2 × 260m = 520m
speed = 3 km / hour
60min ÷ 3 = 20min (time to walk 1 km or 1000m)
20min ÷ 2 = 10min ( time to walk 500m)
20min ÷ 20 = 1 min or 60 seconds (time to walk 50 m)
60 sec ÷ 10 = 6 sec (time to walk 5m)
5m × 4 = 20 m ( 24 seconds)
answer = 10 min 24 seconds
