Average Speed = Distance / Time Taken
Average Speed = 80 km/h + 50 km/h
Time = 1.5 hr + 30 mins
Average Speed = 130 km/h / 2 hr
= 65 km/h is the Average speed of the automobile.
Average Speed = 80 km/h + 50 km/h
Time = 1.5 hr + 30 mins
Average Speed = 130 km/h / 2 hr
= 65 km/h is the Average speed of the automobile.
