does this graph make sense :)?

i dont know if i made the right kind of graph some input would be nice

here is the orginal problem

3. A swimmer floats on the surface of a completely filled 10-foot deep pool for 5 seconds. He then takes 3 seconds to swim to the bottom of the pool and 2 seconds to return to the surface, where he then floats for another 5 seconds. After that, his watch slips off and he swims halfway to the bottom to grab it. It took him 1 second to grab the watch and another 1 second to swim back to the surface.

Draw a graph that models the swimmer’s depth below the water’s surface over time.

Right graph but...


5 to 8 is 3 seconds

8 +2 = 10 at the top at 10

10 + 5 = 15 still at the top

15 + 1 to grab the watch and one to swim up = 17
,,,,,,,,,,,,,,,,

It should be at 8 at the bottom not 9 and so on.......

5,8,10,15,17
