An expressway is 336 kilometers long. A passenger car completes the whole journey in 3.2 hours and a truck completes the whole journey in 4.8 hours How fast is the bus faster than the truck?
Speed of passenger car = 336 / 3.2 = 105
Truck speed = 336 / 4.8 = 70
The speed of passenger cars is 105-70 = 35 (km) faster than that of freight cars
A highway is 336 kilometers long. A bus runs the whole journey in 3.2 hours and a truck runs the whole journey in 3.8 hours. How much faster is the speed of the bus than that of the truck? Relation: The required speed of passenger cars is much faster than that of freight cars, which must be calculated first: The formula does not need to be calculated:
Relationship: speed of passenger car - speed of freight car = speed of passenger car faster than freight car; The speed of passenger cars is required to be faster than that of freight cars. We must first calculate the speed of passenger cars and freight cars. The formula is 336 ÷ 3.2-336 ÷ 3.8 ≈ 105-88.42 = 16.58 (km). A: the speed of passenger cars is faster than that of freight cars

Relationship: speed of passenger car - speed of freight car = speed of passenger car faster than freight car;
The speed of the passenger car is required to be much faster than that of the freight car, which must be calculated first: what is the speed of the passenger car and what is the speed of the freight car,
The formula is: 336 ÷ 3.2-336 ÷ 3.8
≈105-88.42
=16.58 (km)
A: the speed of passenger cars is 16.58 kilometers faster than that of trucks
Therefore, the answer is: the speed of passenger cars - the speed of freight cars = the speed of passenger cars faster than freight cars; What is the speed of the passenger car and what is the speed of the freight car; 336÷3.2-336÷3.8．

A highway is 336 kilometers long. A bus runs the whole journey in 3.2 hours and a truck runs the whole journey in 3.8 hours. How fast is the speed of the bus faster than that of the truck? 336÷3.2—336÷3.8 Because 336 ÷ 3.8 can not be divided completely, I think of such a formula. Please take a look: Use 336 first × （3.8—3.2）=201.6 （336—201.6）÷（3.8+3.2）=16.8
Your formula is wrong
The distribution rate can only be used in multiplication, not division
If you want to use the allocation rate, it is as follows:
336÷3.2—336÷3.8
=336 × 1/3.2—336 × 1/3.8
=336 × （1/3.2—1/3.8）
=315/19
Because 3.8 has a factor of 19, but 336 doesn't, and it doesn't disappear when subtracted from 1 / 3.2, so this problem can't be eliminated
The two trains leave from the two places 600 kilometers apart and meet in three hours. It is known that the speed of the fast train is 1.5 times that of the slow train How many kilometers do the express and the local trains travel per hour?
Idle speed
＝（600÷3）÷（1.5+1）
＝200÷2.5
= 80 (km / h)
Speed of express train
＝80 × one point five
= 120 (km / h)
