RRB NTPC · Question 64

Mrs. Vijaya takes a total of 9 hours 50 minutes in walking a distance and running back to same place where she started. She could walk both ways in 12 hrs 20 minutes. The time taken by her to run both ways is:

  1. 7 hours 45 min

  2. 7 hours 35 min

  3. 7 hours 15 min

  4. 7 hours 20 min

Show answer & explanation

Answer: (D) 7 hours 20 min

Explanation

Walking both ways takes 12 h 20 min, so one way on foot = 6 h 10 min. Running one way = 9 h 50 min − 6 h 10 min = 3 h 40 min, so running both ways = 7 h 20 min.
