A train travels from one station to another at a speed of 40km/hr and returns to the first station at the speed of 60km/hr.calculate the average speed and average velocity of the train
Plz solve to be the brainliest

Answer 1

Hi friend,

➡Complete solution :-

➡Let the distance between two stations = d km

➡After, the journey the train returns to the first station.

➡Total distance travelled = 2d
Net displacement of the train = 0

➡So, the train time taken to travel one station to another station = t1= d/40hrs

Time take by the train when come back , t2= d/60hrs

Therfore, total time taken by the train to round the trip is

t = t1+t2= d/40 + d/60 = d/24hrs

➡Avg . Speed = 2d/ d/24 = 48 km/ h

➡Avg. Velocity = 0/ d/24 = 0 km/ h
