Solution
Time taken to cover 375 km = (375/75)h = 5h
Number of stoppages = 375/125-1 = 2
Total time to stoppages = (5 × 2 ) min = 10 min
Hence, total time taken = 5 h 10 min
Time taken to cover 375 km = (375/75)h = 5h
Number of stoppages = 375/125-1 = 2
Total time to stoppages = (5 × 2 ) min = 10 min
Hence, total time taken = 5 h 10 min
