1, Xiaolong speed is x, Xiaoming speed is y, S=2(X+Y)+36, 2(X+Y)=36*2.

So S= 108.

2. Set up * * to buy X sets.

(32000/(X/3)+ 10)*(2X/3)= 68000

X=600

3. Robot A carries X kinds of chemical raw materials every hour, and robot B carries Y kinds of chemical raw materials every hour.

X=Y+30

900/X=600/Y

x = 90°

Y=60

It takes X days for Team A to complete this task alone, and X+2 days for Team B to complete this task alone.

The total amount is 1

2 *( 1/X)+3 * 1/(X+2)= 1

X=4
