Answer 2

Answer:Yes,  a body can have constant speed but variable velocity.

Explanation: If a body is moving in zig-zag road in constant speed or in a road with many turns in constant speed than the body has constant speed but variable velocity. As speed is distance/time the body is  equal distance in equal time. Whereas, velocity is displacement/time. Displacement is shortest path to reach a point. In the above cases  unequal displacement is covered in equal time. So,the velocity is variable.
