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

koban [17]

Their beginning time was 16.06 minutes.

<u>Step-by-step explanation:</u>

The track team is trying to reduce their time for a relay race.

First they reduce their time by 2.1 minutes, take it as $t_{1}$ . Then they are able to reduce that time by 10 minutes, take it as $t_{2}$ . Let ‘X’ be the time in minutes at the beginning.

Given that their final time is 3.96 minutes, then their beginning time can be calculated as below,

$X-t_{1}-t_{2}=3.96 \text { minutes }$

$X=3.96+t_{1}+t_{2}$

By substituting the values, we get

$X=3.96+2.1+10=16.06 \text { minutes }$

Hence, their beginning time was 16.06 minutes.
