Answer:
Answer:
6.5 hrs
Step-by-step explanation:
Bus = 180 km, at speed of 40 km/hr, if Speed = Distance /Time,
Time = Distance/Speed
therefore time taken to travel with bus = 180/40 hrs = 4.5 hrs
Train = Distance left to be covered = (320 - 180) = 140 km
Time = Distance/Speed
therefore time taken to travel with train = 140/70 = 2 hrs
Therefore total time = 4.5 hrs + 2 hrs
= 6.5 hrs
