Question

What am I supposed to do here

Answer 1

First, you take Distance/Time
for ex, 5/1=5
Keep doing like that and when you finished
Take Time/Distance
For ex, 2/10=1/5

Answer 2

So the clue is 5 for 25 now divide the distance which is 25 over 5 which is the time so for every 1 min you go 5 m.
