8:40 am 17

How can I estimate the average river current speed from 8:00 am to 8:40 am using the trapezoidal rule? I tried but I got a huge number.

I converted 8:40 into hours so 40/60=2/3

Then I supposed 0 to be 8:00, so the equation I had was integral sign 0 to 2/3 S(t) dt.

Then using the data in the chart: (17+2(20)+2(22)+2(21)+17)

Then I multiplied that sum by 1/(b-a) to get the average, and I got a number in the hundreds.
