A walk a certain distance and ride back taking a total time of 37 minutes. A could walk both ways in 55 minutes. How long would it take me to ride both ways ?

Answer:

Explanation:

Let the distance be $x$ km. Then,

(Time taken to walk $x$ km) + (Time taken to ride $x$ km) = 37 min.

$\Leftrightarrow$ (Time taken to walk $2x$ km) + (Time taken to ride $2x$ km) = 74 min.

But, time taken to walk $2x$ km = 55 min.

Time taken to ride $2x$ km $=(74-55)$ min = 19 min.
