It is known that the speed ratio of train a and B is 14:15, and train a runs 56 kilometers per hour How many kilometers are the two stations apart?

It is known that the speed ratio of train a and B is 14:15, and train a runs 56 kilometers per hour How many kilometers are the two stations apart?

14 to 15 is 56 times 5 than x times 5
14 to 15 is 280 to 5x
70X equals 4200
X equals 60
[56 + 60] times 5
It's 580
Answer: the distance between the two stations is 580 kilometers
Car a 56 times 5 equals 280 km
Car B 60 times 5 equals 300 kilometers
The ratio of boxes of chalk in box a and Box B is 5:1. If 12 boxes are taken out of box a and put into Box B, the ratio of boxes of chalk in box a and Box B is 7:5, then how many boxes are there in total?
12 (55 + 1-77 + 5), = 12 (56 − 712), = 12 (14), = 12 × 4, = 48 (boxes); answer: there are 48 boxes in two cases of chalk
The distance between the two places is 60 km, and the speed ratio of the two cars is 4:5 per hour
Speed sum of two cars: 60 △ 2 / 3 = 90km
A speed: 90 △ 4 + 5 X4 = 40 km
B speed: 90-40 = 50 km
Car a travels 40 kilometers per hour, and car B travels 50 kilometers per hour
There are 550 tons of goods in a station, and a team has worked for 3 hours in the morning and transported 330 tons. According to this calculation, how many hours will the rest be transported? (using proportional solution)
Please, please
Let the rest take x hours
330:3=(550-330):x
330x=660
X=2
x/(50-330)=3/330
Let the rest be transported in X hours, then 330 / 3 = (550-330) / X solves x = 2, that is, it will be transported in 2 hours
Let the rest take x hours
330:3=(550-330):x
330x=660
X=2
The radius of a sector is 4 decimeters, and the central angle is one eighth of the circumference. How many square decimeters is the area of this sector?
4x4x3.14x1/8 = 6.28m2
One hundred and twenty
If the center angle is 1 / 8 of the circumference angle, it is 360 * 1 / 8 = 45, and the sector area = π R ^ 2 * 45 / 360
2 π square decimeter
4 ^ 2 * 1 / 8 * circle law = circle law multiplied by two
A. The distance between B and B is 96 km. The two cars of a and B are facing each other from AB and meet each other in two-thirds of an hour. It is known that the speed ratio of a and B is 5:4,
How many kilometers did a and B travel when they met?
96 △ 2 / 3 = 144 (km / h) the combined speed of two cars is 144 × 5 / (5 + 4) = 80 (km / h) the speed of car a is 144 × 4 / (5 + 4) = 64 (km / h) the speed of car B is 80 × 2 / 3 = 160 / 3 = 53 and 1 / 3 (km) when meeting, the walking distance of car a is 64 × 2 / 3 = 1
A:
96 ÷ (5 + 4) × 5 = 160 / 3km
B:
96-160 / 3 = 128 / 3 km?
Five trucks of the same model can transport 75 tons of goods in three times. Now a supermarket is in urgent need of 200 tons of goods. How many trucks do you need in total? How many more?
Hello: each vehicle needs 200 / 2 / 5 = 20 vehicles with 75 / 3 / 5 = 5 tons each time. Add 20-5 = 15 vehicles ~ if you agree with my answer, please click the [adopt as satisfactory answer] button in time ~ ~ the mobile phone questioner can comment on [satisfied] in the upper right corner of the client. ~ your adoption is my driving force ~ ~ ~ if there are any new ones
What is the speed ratio of minute hand to hour hand on a clock______ .
Because the clock rotates 1 block clockwise, the minute hand just rotates 12 blocks, so the speed ratio of the minute hand and the hour hand is 12:1, so the answer is: 12:1
The distance between the two cities is 330km. Two cars of a and B come out from the two places at the same time, and they meet three hours later. It is known that the speed ratio of a and B is 6:5, and the speed ratio of a and B is 6:5
How many kilometers per hour
Two cars per hour 330 △ 3 = 110 km
A: 110 △ (6 + 5) X6 = 60 km / h
B 110-60 km / h = 50 km
If you don't understand this question, you can ask,
Three trucks transport 75 tons of goods in five times. In this way, thank you for three more times. How many tons of goods can be transported?
75 / 5 / 3 = 5 (ton)
5 * 3 = 15 (ton)
