Answer 2

Answer:

50.5kmph

Explanation:

easy

see phele train A se B gayi

with speed=60kmph time=0.52h

so by using speed=distance upon time formula

we get distance between A and B is 31.2km

now train travels from B to C

with speed 30kmph for 0.24h

so distance BC=7.2km

now total distance covered by train is 31.2+7.2=38.4km

total time equal to 0.52+0.24=0.76 h

so avg speed=38.4/0.76=50.5kmph
