It travels first 30 km at a speed of 60 km/hr.
Time = Distance/Speed
= 30/60 = 30 minutes.
It travels another 30 km at a speed of 40 km/hr.
Time = 30/40 = 45 minutes
Therefore, Total time taken = 30 min + 45 min = 1 hour 15 minutes
Time = Distance/Speed
= 30/60 = 30 minutes.
It travels another 30 km at a speed of 40 km/hr.
Time = 30/40 = 45 minutes
Therefore, Total time taken = 30 min + 45 min = 1 hour 15 minutes
