A man travels by bus for 20 hours and they by train for 05 hours. if the average speed of the bus was 20 kmph and that of the entire journey was 24 kmph. What was the average speed of the train?
44kmph
30 kmph
36 kmph
40 kmph
Explanation:
Total distance travelled = 24 $\times$ (20+5) = 600 kms
distance travelled by bus = 20 $\times$ 20=400 kms
distance travelled by train = 600-400=200kms
Average speed of train = 200/5=40 kmph.
