Hope this helps ^^
There are three elements in that set.
The best way to solve this one is with a proportion:
(15 steps) / (5 minutes) = (75 steps) / ('x' minutes)
Cross-multiply the proportion: 15 x = 5 x 75
Divide each side by 15 : x = 5 x 5 = <em>25 minutes</em>.
You are correct, and Paul walks very slowly.
