The track team is trying to reduce their time for a relay race. first they reduce their time by 2.1 minutes. then they are able to reduce that time by 10 if their final time is 3.96 minutes, what was their beginning time? show or explain your reasoning.

Using the appropriate arithmetic operation, the beginning time would be 15.97 minutes.

Given the following information :

Expressing the information thus :

v - t1 - t2 = final time

v - 2.1 - 10 = 3.96

v - 12.1 = 3.96

v = 3.96 + 12.1

v = 15.97 minutes.

Hence, the beginning time is 15.97 minutes.
