Car a runs 60 kilometers per hour for X hours; car B runs 58 kilometers per hour for y hours 58y denotes (); X-Y denotes (); 60x + 58y denotes () How do you write it?

58y means (b) the distance in Y hours;
X-Y is the time when a has more lines than B;
60x + 58y refers to the distance and distance that Party A and Party B have passed

The truck is moving at a speed of 40 kilometers per hour, and the car is 58 kilometers per hour. How many kilometers is the distance between the two cars one second before the car catches up with the truck

Distance = (58-40) × 1 / 3600 = 0.005 km

Car a and B start from a to B at the same time. Car a travels 58 kilometers per hour and car B 53 kilometers per hour. Car a stops for 2 hours on the way and ends up at the end of the day
How many kilometers is the distance between a and B?

Let a and B be x km apart,
Then (x / 53) - 2 + 1 = x / 58, and the solution is x = 614.8km

The passenger cars and freight cars run from the two places with a distance of 13 kilometers at the same time. The passenger cars run 58 kilometers per hour, and the freight cars run 46 kilometers per hour. After a few hours, the distance between the two cars is 553 kilometers

After setting x hours, the distance between the two vehicles is 553 km
Then 13 + 58x + 46x = 553
104x=540
X = 5.19 hours
Have a good time

There are two warehouses A and B. warehouse A has 360 tons more grain than warehouse B, and warehouse B has one fifth less grain than warehouse A. warehouse A and warehouse B used to have two warehouses respectively
How many tons of grain are there

The grain stored in warehouse B is one fifth less than that in warehouse A, which means that warehouse A has 1 / 4 more grain than warehouse B
Warehouse B: 360 / (1 / 4) = 1440 tons
Warehouse A: 1440 + 360 = 1800 tons

The quantity of coal in warehouse A and warehouse B is the same. If the quantity of coal in warehouse A is one fourth of that in warehouse B, the quantity of coal in warehouse A is several percent less than that in warehouse B
If the coal in Bin A is transferred to a quarter of that in Bin B

Let a 1, B 1
A = 1-1 / 4 = 3 / 4
B = 1 + 1 / 4 = 5 / 4
B-A = 1 / 2

780 tons of coal coexisted in warehouse A and warehouse B. after 108 tons of coal were transported from warehouse B, warehouse B was 32 tons less than 60% of the coal stored in warehouse A. how many tons of coal was originally stored in warehouse a

1. 780-108 + 32 = 704 (tons)
704 △ 1.6 = 440 (tons)
780-440 = 340 (tons)
A 440 tons, B 349 tons
2. Let a be X
X+0.6X-32=780-108
1.6X=704
X=440
780-440=340
A 440 tons, B 349 tons

If a warehouse transports 15 tons of coal every day and B warehouse transports 25 tons of coal every day, a few days later, B warehouse will store twice as much coal as a warehouse? If x days later, the coal stored in warehouse B is twice as much as that in warehouse A, then ()
A. 2×15x=25xB. 70+25x-15x=200×2C. 2（200-15x）=70+25xD. 200-15x=2（70+25x）

Suppose that after X days, the coal stored in warehouse B is twice as much as that in warehouse A. according to the meaning of the question, we can get 2 (200-15x) = 70 + 25X, so we choose C

There are 1000 tons of coal in warehouse A and warehouse B. 100 tons are consumed by warehouse A and 3 / 5 by warehouse B. at this time, warehouse A is twice as much as warehouse B. how many tons are there in warehouse A and warehouse B

Let a have X tons of coal and B have y tons
Then the equations can be obtained
x+y=1000
x-100=2*(2/5)*y
Solution
x=500
y=500

There are two warehouses A and B. the quality of goods in warehouse A is 80% of that in warehouse B. the goods in warehouse A are 150 tons less than those in warehouse B
How many tons of goods are there in the two warehouses

Suppose B x tons, then a 0.8x tons
8 x = 150
So a 750 × 0.8 = 600
A: a 600 tons, B 750 tons

Car a runs 60 kilometers per hour for X hours; car B runs 58 kilometers per hour for y hours 58y denotes (); X-Y denotes (); 60x + 58y denotes () How do you write it?
