Larissa practices for a swimming tournament

scoundrel [369]

Answer:

Larissa takes 59.141 seconds to complete both laps.

Step-by-step explanation:

The complete time is the sum of time taken on each lap. We translate the two statements into mathematical expressions to determine the required output:

(i) <em>She completes her first lap in 31.135 seconds</em>:

$x_{1} = 31.135\,s$

(ii) <em>She completes her second lap 3.129 seconds faster than the first lap</em>:

$x_{2} = x_{1}-3.129\,s$

$x_{2} = 31.135\,s - 3.129\,s$

$x_{2} = 28.006\,s$

Then, the time taken by Larissa to complete both laps is:

$\Delta x = x_{1} + x_{2}$

$\Delta x = 31.135\,s+28.006\,s$

$\Delta x = 59.141\,s$

Larissa takes 59.141 seconds to complete both laps.
