I walk a certain distance and ride back taking a total time of 37 minutes. I could walk both ways in 55 minutes. How long would it take me to ride both ways?
-
- 9.5 minutes
- 19 minutes
- 18 minutes
- 20 minutes
Correct Option: B
Two ways walking time = 55 min ...(i)
One way walking + One way riding time = 37 min. ....(ii)
By 2 × (ii) – (i),
2 ways riding time
= 2×37–55 = 19 minutes
