Practical questions (formulas and answers) 1. 36 workers, each of whom can process 10 class a parts or 16 class B parts every day. Two class B parts and one class a part form a set. How many people should be arranged to process class a parts and class B parts respectively every day, so that the two parts can be fully matched 2. The sea route from a to B is nearly 40 kilometers than the highway. At 10 a.m., a ship sails from a coastal road to B, and at 1 p.m., a car also sails from a to B along the highway, and arrives at the same time. The ship is 24 kilometers per hour, and the car is 40 kilometers per hour. How long is the highway from a to B

1. Suppose x people produce type a parts and (36-x) people produce type B parts
10X=（36-X）*18/2
X = 16
16 people produce type a parts, 20 people produce type B parts
2. If the sea route is x km, the highway is (40 + x) km
X/24-（40+X）/40=3
X = 240
Then the highway length is 240 + 40 = 280 km
