An effective rainfall of 2 hour duration produced a flood hydrograph peak of 200 m³/s. The flood hygrograph has a base flow of 20 m³/s. If the spatial average rainfall in the watershed for the duration of storm is 2 cm and the average loss rate is 0.4 cm/hour, the peak of 2-hour unit hygrograph (in m³/s-cm up to one decimal place) is
