Step-by-step explanation:
total distance/total time
180+125+150/3+2+3×1/2
455/5+3×1/2
455/5+3/2
455×2/5+3
455×2/8
910/8
113km/h
Thanks for A2A
Total Distance = 150 km + 125 km + 180 km = 455 km
Average Speed = Total Distance/ Total Time
In this case
Total Time = 3 hours + 2 hours + 3.5 hours = 8.5 Hour
Average Speed = 455/8.5 Kmph = 53.5294 Kmph
Good Luck
Step-by-step explanation:
The train covers total distance in three legs , first 150 km. In 3 hours , next 125 km in 2 hours and last 180 km in 3 hours 30 minutes
We know Average speed = total distance / total time
Average Speed = 53.53 km/hour
The average speed of the train is 53.53 km/hr.
Answer :The average speed of the train is 53.53 km/hr.
Total distance in three legs = 150 + 125 + 180 kns = 455 kms.
Total time = 3 hours + 2 hours + 3 hours 30 minutes = 8 hours 30 minutes = 8.5 hours
Average Speed = 455 km / 8.5 hours
