Answer:

(c) 31.37 seconds

Explanation:

You want to know how much time Jodie has left to match a record time of 73.4 seconds if she has already spent 30 1/4 seconds and 11.78 seconds on two of the obstacles of the course.

Available time

The time Jodie has available is the difference between the total time target and the time already spent:

73.4 -30.25 -11.78 = 31.37 . . . . seconds

Jodie has 31.37 seconds left to match the course record.
