The second is the available units and the exact tolerance needed

Two streams merge to form a river. One stream has a width of 8.3 m, depth of 3.3 m, and current speed of 2.4 m/s. The
other stream is 6.2 m wide and 3.8 m deep, and flows at 2.5 m/s. If the river has width 11.7 m and speed 2.9 m/s, what is its
depth?
