Question

The track team is trying to reduce their time for a relay race. First, they reduce their time by 2.1 minutes. They are able to reduce that time by 1/10. If their final time is 3.96 minutes, what was their beginning time?

Answer 1

6.27 minutes

Explanation:

1/10 of 2.1 is 0.21 and 2.1+0.21=2.31 and if there final time is 3.96 then to find the original time you must add them 2.31+3.96=6.27
