Answer:
Option A
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.
