Question

320 km distance is to be covered partially by bus and partially by train. Bus covers 180 km distance with a speed of 40 km/hour and the rest of the distance is covered by train at speed of 70 km/hour. Find the time taken by a passenger to cover the whole distance?​

Answer 1

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
