No OK let's see how long Is the debate, the second debate started 20 late then it started at 5:10 so to know the length of the debate we should subtract the 2 shows so 5:10-3:15 = 1:55 minutes we also should subtract 30 m because of the break so 1:55-30 = 1:25 minutes so the show length is 1:25 minutes so to know when the 2nd show will end we should add 5:10+1:25 = 6:35 p.m

Carl can paint a room 3 hours faster than Jennifer can

Nata [24]

Jen take x hours.
Carl (x-3)hours.
Jen+carl take two hours;
This means;
In 1 hour, for they work
$\frac{1}{x} + \frac{1}{x-3}$
= $\frac{(x-3)+x}{x(x-3)}$
= $\frac{2x-3}{x(x-3)}$
Working together, they take two hours;
Take reciprocal of above equation and equate to two;
= $\frac{x(x-3)}{2x-3} =2$
$x^{2}$ -3x=4x-6
$x^{2} -7x+6=0$
$x^{2}$ -x-6x+6=0
x(x-1)-6(x-1)=0
(x-6)(x-1)=0
Take the bracket x-6=0 so that Carl works positive hours
x-6=0
x=6
