Question:
Sneha walks a certain distance and ride back taking a total time of 37 minutes. She walks both ways in 55 minutes. How long would it take her to ride both ways ?
Options:
A) 19 minutes.
B) 20 minutes.
C) 9.5 minutes.
D) 18 minutes.
Solution:
We are given that Sneha walks both ways in 55 minutes.

therefore,  She walks a certain distance in = 55/2 minutes = 27.5 minutes

Hence,  Time takes in riding the same distance = 37-27.5 = 9.5 minutes.
