Answer:
Total time = 86 seconds
Step-by-step explanation:
There are three persons in relay race. In relay race every athlete has to complete one lap of the race and total time take taken by each individual becomes the race time.
Now it has been given that the time taken by the runners are 28.7 seconds, 29.4 seconds and 27.9 seconds.
Therefore, total time = 28.7 + 29.4 + 27.9
= 86 seconds.
Total time taken = 86 seconds
