The expression in (a) represents the time taken for travel from Ahmed to John.

2 seconds represent the delay in throwing.

The expression in (b) represents the time taken for travel from John to Pierre.

Altogether, these events take a total of 7 seconds.

We simply add the three terms together and then do algebraic manupulation.
