Positioning or speed?
Are you trying to measure the position (angle) of a shaft, or the speed of rotation. As Rob says, they will work for speeds like yours.
If you want position or the angle, like for a steering system, then the problem with these is the low resolution. Most have 16-32 "codes" per rotation. This means you can only get the position to +/- 1/32 of a rotation (~11 deg.). To get more resolution, you could connect one with a belt or gears so that the encoder rotated more than the shaft being measured, more complex.
