How to solve this Riddler's riddle I don't know what to do? (Batman: Arkham Knight)

Have you tried it with a Batmobile (detonate, apply current, etc.)?

Pull out the platform with the Batmobile and apply the gel. Pull the platform back and blow it up.

Thanks, I figured it out, but how do I solve this one?

There is a guide for all the riddles. Videos for each large section. Specifically, this riddle is a race. Elsewhere on the map, there is a switch that you need to activate and return to the trophy in the allotted time and pick it up before the grate slams shut again.

there are numbers next to it, you remember and look for it in the map, since these are coordinates. You come to the place, apply current / stand on the button and run back. I found all the questions myself, only searched for riddles in the city on the sites.
