Question

the table below gives te depth of water across a river measured at one metre intervals between banks. distance (m) 0 1 2 3 4 water depth (m) 0 0.5 1.6 0.9 0 use the trapezium rule to estimate the cross-sectional area of the river. a river hydrologist estimates that at the place where this cross sectional data was measured the average speed of water flow is 0.6m/s estimate the volum of water which passes this section of the river in one minute.
