Answer:
The beginning time of relay race is 6.73 minutes
Step-by-step explanation:
Given as :
The final time of relay race = 3.96 minutes
Let The initial time of relay race = x minutes
At first, The time reduce by 2.1 min
So, The first time become = ( x - 2.1 ) min
At second , The time reduce by = 0.1
So, The time become = ( x - 2.1 ) min - min
Or,
∵ final time of race = 3.96 min
∴ = 3.96
Or, 9 x - 21 = 3.96 × 10
Or, 9 x = 39.6 + 21
Or, 9 x = 60.6
∴ x =
i.e x = 6.73 minutes
So, The beginning time = x = 6.73 min
Hence,The beginning time of relay race is 6.73 minutes Answer
