Radius of circular bowl = 400 /2 = 200mm
Speed of pulse = 250mms-1
In 1 second, the distance travelled by the pulse would be
Distance travelled = Speed x Time = 250 x 1 = 250mm
However, the pulses formed on the surface of the water would reflect each other at the centre of the circular bowl, where they meet. So, any specific pulse would move (from the side of the bowl) to the centre of the bowl (a distance of 200mm from the side of the bowl), and then it gets reflected back (now moving towards the side of the bowl).
In 1 second, a pulse moves a total distance of 250mm. For the first distance of 200mm, it moves inwards (towards the centre). Thus, for the remaining 50mm, the pulse is moving outwards, at a radius of 50mm.
