It sounds like you are using YouTube App to watch YouTube videos. Mobile versions often have much less functionality. With the official YouTube app there is (currently) no function to control the speed of a video.
To get that functionality on your iPad please use Chrome web browser to access YouTube.
Go to App Store -> download "chrome".
Open it and go to youtube.com.
On the top right there are three dots -> request desktop site
If you play the video you should be able to see the gear on the bottom right of the video player
