To approximate that place, an intuitive strategy could be to divide up the distance involving a and b into a number of equivalent segments, the length of every section represented via the symbol Δx. For every tiny section, we can easily choose one price of the perform file(x). Phone that benefit h. Then the area with the rectangle with foundation Δx and peak h gives the gap (time Δx multiplied by speed h) traveled in that section.
