A train takes 80 minutes to travel from station p to q and another 40 minutes to return from q to p if the distance between p to q is 60 km calculate average speed 2.averge velocity of train.
Answers
Answer:
Answer -
Average speed = 60 km/h
Displacement = 0 km
Average velocity = 0 km/h
◆ Explaination -
Total distance covered is calculated by -
Distance = 60 + 60
Distance = 120 km
Total time taken for journey is -
Time = 80 + 40
Time = 120 min
Time = 2 hrs
Average speed of the train is -
Average speed = distance / time
Average speed = 120 / 2
Average speed = 60 km/h
Displacement of the train is zero as train returns at its original point of arrival.
Average velocity of the train is zero as its displacement is zero.
Answer:
Average speed = Total Distance covered/ Total Time Taken
When the distance is constant: Average speed = 2xy/x+y; Where, x and y are the two speeds at which the same distance has been covered.
When time taken is constant: Average speed = (x + y)/2; Where, x and y are the two speeds at which we traveled for the same time.
Time and Distance Formula
Distance = Speed × Time. Using this formula, all basic problems can be handled. However, you need to make sure about the correct usage of units while using the above formulas.
Speed is inversely proportional to the time taken when distance travelled is constant. So when speed increases, time decreases and vice versa.
