Question #28560

1. The table below gives the 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 volume of water

which passes this section of the river in one minute.
