Four friends, Jason, Bill, Art, and Pablo, ran a 100-yard race. Jason ran the race in 17.32 seconds. Bill ran the race 1.78 seconds faster than Jason. Bill's time was 0.84 seconds more than Art's. Pablo's time was 1.23 seconds less than Bill's. Who had the winning time?

17.32 seconds

Step-by-step explanation:

To solve this problem we need to the instances given:

  Number of friends  = 4;

  Distance covered  = 100yards

Now, sentence by sentence;

  Jason ran the race = 17.32 seconds

Bill ran the race 1.78 seconds faster than Jason;

  Bill's time = 17.32 + 1.78  = 19.1 seconds

Bill's time was 0.84 seconds more than Art's;

    Art's time  = 19.1 + 0.84  = 19.94 seconds

Pablo's time was 1.23 seconds less than Bill's,

   Pablo's time  = 19.1 - 1.23  = 17.87 seconds

The winning would be that of the friend with the lowest time, the lower the time higher the speed.

So Jason's time is the winning time =  17.32 seconds
