The first pic is the question the second pic is the answer pls help me teachers i need a solution 3. 121 m/sec24.5 sec. 3. Hiroki is calculating the speed of a tsunami. The formula in speedis s = V9.8d where d is ocean depth in meters. In this case, theocean was 1500 m deep. How fast was the wave (in m/sec2. )4. Marissa dropped her sunglasses from a bridge 400 ft. above theriver. Use the formula t=to find how many seconds it took forthe sunglasses reach the river.

3.) Given : d=1500m (ocean depth) The formula of speed is : s=9.8ds=14700=121 m/s
