The ratio of speeds for walking, cycling, and running is given as 1 : 9 : 3.

We know that speed is inversely proportional to time taken when the distance is constant. This means that if the speed is higher, the time taken is less and vice versa.

So, the ratio of times taken for walking, cycling, and running would be the inverse of the speed ratio.

Therefore, the ratio of times taken would be 1/1 : 1/9 : 1/3, which simplifies to 9 : 1 : 3.

So, the correct answer is 9 : 1 : 3.
