An express traveled at an average speed of 100 km/hr, stopping for 4 min after every 75 km. How long did it take to reach its destination 150 km from the starting point ?
Answer/Solution
1 hr 34 min
Steps/Work
Explanation:
Time taken to cover 150 km = 150/100 = 1 hr 30 mins
Number of stoppages = 150/75 - 1 = 1
Total time of stoppages = 4 x 1 = 4 min
Hence, total time taken = 1 hr 34 min.
Answer: E
Time taken to cover 150 km = 150/100 = 1 hr 30 mins
Number of stoppages = 150/75 - 1 = 1
Total time of stoppages = 4 x 1 = 4 min
Hence, total time taken = 1 hr 34 min.
Answer: E
