The speed, s, in metres per second, of a tsunami, is related to the depth, d, in metres, of the water through which it travels.  This relationship can be modelled with the formulas=√10d, d≥0 A tsunami has a depth of 22 m.  What is the speed as a mixed radical?

sqrt  (10  * 22)    =  sqrt (220 ) =   sqrt  ( 4 * 55)  =    2sqrt (55)   m /s
