Answer:

45.88 seconds

Step-by-step explanation:

$t_1$ = Time taken to sing the fist time = $48.7\ \text{s}$

Time taken to sing the second time was $2.9\ \text{s}$ less than the first time so

$t_2=t_1-2.9\\\Rightarrow t_2=48.7-2.9\\\Rightarrow t_2=45.8\ \text{s}$

Time taken to sing the third time was $0.47\ \text{s}$ less than the the second time

$t_3=t_2-0.47\\\Rightarrow t_3=45.8-0.47\\\Rightarrow t_3=45.88\ \text{s}$

So the time it took the choir to sing the third time was 45.88 seconds.
