Answer:
60 KM
Explanation:
Let us approach this interesting question step by step, hope this will encourage you to actively tackle all your doubts :)
- Calculate the time of travelling the distance of 20km at a speed of 60 km/hr by using the formula
begin mathsize 12px style Speed equals Distance over Time
Time equals Distance over Speed end style
- Similarly, calculate the time of travelling the distance of 40km at a speed of 80 km/hr by using the same formula.
- Add up both the time durations to get a total time of travel, also, add the total distance of travel (i.e 20 km +40 km = 60 km)
- Substitute the values of total time of travel and the total distance of travel in the above-mentioned formula to get the average speed of the train.
