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.

Hence, their beginning time was 15.7 minutes.

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.
