Ateam of 4 people participates in a 400-yard relay race. each team member runs the same distance. the team completes the race in a total of 53.2 seconds. what is the average running time for each person?

Number of people participating in the relay race = 4
Total distance ran by 4 people of a team = 400 yards
Let us assume the distance run by each member = x yards
Then
4x = 400
x = 400/4
x = 100 yards
Total time taken to rum the full distance = 53.2 seconds
Average running time of each person = 53.2/4
                                                            = 13.3 seconds.
