To approximate that space, an intuitive approach will be to divide up the distance among a and b into a number of equivalent segments, the duration of each and every segment represented via the symbol Δx. For each small segment, we can choose one worth of the functionality f(x). Phone that price h. Then the world on the rectangle with foundation Δx and top h presents the space (time Δx multiplied by speed h) traveled in that phase.
