Question

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 1/10. If their final time is 3.96 minutes, what is their beginning time?

Answer 1

Answer:

6.27

Step-by-step explanation:  1/10 × 2.1= 0.21. 3.96+0.21= 4.17. 4.17= the time after the beginning time so then you have to do 4.17+2.1=6.27.

so the beginning time was 6.27
