Woman's Daily Commute
Morning Walk: 9:00 am - 9:30 am (5 km/h for 2.5 km)
At Office: 9:30 am - 5:00 pm (7.5 hours)
Evening Return: 5:00 pm - 5:06 pm (25 km/h for 2.5 km)
Total distance: 5 km (2.5 km each way)
Time Calculations
Walking Time:
2.5 km / 5 km/h = 0.5 h = 30 min
2.5 km / 5 km/h = 0.5 h = 30 min
Auto Time:
2.5 km / 25 km/h = 0.1 h = 6 min
2.5 km / 25 km/h = 0.1 h = 6 min
Office Duration:
7.5 hours (9:30 am - 5:00 pm)
7.5 hours (9:30 am - 5:00 pm)
