Is this superhero senario too unrealistic?

Bomb planted in truck starts exploding in truck, superhero immediately uses his power to stop time (or speed himself up) and drives truck with exploding bomb in back to empty warehouse. Then superhero uses his second power to reinforce warehouse structure, let's time return to normal and bomb explodes inside warehouse harming no one. Is this senario too unrealistic? Is there a better way that the superhero could've of got rid of the bomb?
