Can a body have a constant velocity but varying speed?

No. Speed of a body is the overall distance travelled per unit time; irrespective of its direction. Velocity of a body is the overall displacement occured per unit time; with regard to its direction. If a body is moving with a constant velocity, then its magnitude and direction remain constant. Speed is the magnitude of velocity. Therefore, speed also remains same.
