Biking Phase- Speed: 6 km/h Time: 2 hours Distance traveled = Speed × Time = 6 km/h × 2 hours = 12 km Walking Phase- Speed: =2 km/h Time: = 1 hour Distance traveled = Speed × Time = 2 km/h × 1 hour = 2 km Rest and Lunch Phase- Time: 1 hour for rest + 0.5 hours for lunch = 1.5 hours Since there's no movement, this time adds to the total time but not to the distance. Garden Visit Phase- Speed: 1 m/s (which needs to be converted to km/h for consistency). Since 1 m/s = 3.6 km/h, Distance traveled = Speed × Time = 3.6 km/h × 1 hour = 3.6 km Returning Home Phase- Speed: 4 km/h Time: 3 hours Distance traveled = Speed × Time = 4 km/h × 3 hours = 12 km Total Distance Traveled = 12 km (Biking) + 2 km (Walking) + 3.6 km (Garden Visit) + 12 km (Returning Home) = 29.6 km Total Time Spent (including resting and lunch breaks) = 2 hours (Biking) + 1 hour (Walking) + 1.5 hours (Rest and Lunch) + 1 hour (Garden Visit) + 3 hours (Returning Home) = 8.5 hours Average Speed = Total Distance Traveled / Total Time Spent Average Speed = 29.6 km / 8.5 hours ≈ 3.48 km/h
