1. The problem statement, all variables and given/known data

2. Relevant equations

3. The attempt at a solution

An arrow is shoot up in the air at 50m/s. Its height in meters after t sec. is h=50t-0.36t^2. Find the average velocity over interval [1,1.03], four decimal places.

this may help (if I remember it correctly)

$$F(x)_{average}=\frac{1}{b-a} \int_{a} ^{b} f(x) dx$$

I think this is a simple secant problem where you find the average rate of change between the two points (1, h(1)) and (1.03, h(1.03)) and not the average value of the function.
