16x/2= 10(85-x)/3
8x= 10(85-x)/3
24x=850- 10x, 34x=850, x=25 (person), 85-x=60 (person).
A: Arrange 25 people to process A parts and 60 people to process B parts.

(1) The whole journey time of tortoise is: 10000 ÷ 40 = 250, and that of rabbit is: 10000 ÷ 400 = 25.
250-25=225
If rabbits don't want to lose to turtles, they can only sleep for 225 minutes at most.
1.5 hours =90 minutes
Let time be x, then the equation is: 40X+40*90=400X.
Find X= 10.
Distance = 400 * 10 = 4000m.
