A storage tank receives inflow at a rate (in L/min) measured every minute over a 6-minute period. The data are shown below, where ​t​ is minutes after the start and ​R(t)​ is the inflow rate at that time.

  1. Use the trapezoidal rule with an interval width of ​1​ to estimate the total volume of water that flowed into the tank over the 6 minutes.

    [3]
    Part (a):
    V= L

A high-precision meter later shows the true total was ​112.5​ L.

  1. Calculate the percentage error of your estimate from part (a).
