<h2>The crime gets cleaned up at 2:00 PM</h2>

Step-by-step explanation:

Let the work be w.

Batman can clean up all of the crime in Gotham City in 8 hours working alone.

$\texttt{Rate of batman,}r_b=\frac{W}{8}$

Robin can do the same job alone in 12 hours.

$\texttt{Rate of Robin,}r_r=\frac{W}{12}$

Robin starts work at 8:00 AM and Batman Joins at 10:00 AM.

Let the time of completion of work after Batman's joining be t.

We have time of working of Robin = t + 10:00 -8:00 = t + 2

$t\times \frac{W}{8}+(t+2)\times \frac{W}{12}=W\\\\12t+8t+16=96\\\\20t=80\\\\t=4hours$

After 4 hours of 10:00 Am work gets completed.

Time = 10:00 AM + 4 hours = 2:00 PM

The crime gets cleaned up at 2:00 PM

Answer:

Step-by-step explanation:

12.9 + 10.2x = 35.1

10.2x = 35.1 - 12.9

10.2x = 22.2

x = 22.2/10.2

x= 222/102 = 111/51

$x= 2\dfrac{9}{51}$
