RRB NTPC · Question 76

Hema takes a total of 9 hours 55 min to walk a certain distance and then cycling back to the same place from where she had started. She could walk both ways at the same speed in 12 hours 30 min. The time she will take to cycle both ways is :

  1. 7 hour 20 min

  2. 7 hour 15 min

  3. 7 hour 35 min

  4. 7 hour 45 min

Show answer & explanation

Answer: (A) 7 hour 20 min

Explanation

Walking both ways takes 12 h 30 min, so one way on foot takes 6 h 15 min. Walk + cycle = 9 h 55 min, so cycling one way = 9 h 55 min − 6 h 15 min = 3 h 40 min. Cycling both ways = 7 h 20 min.
