A car has a speed of 50 kilometers per hour. There is a clock which is 3 minutes per hour. If you use the clock to measure the speed of the car, what is the speed of the car?

A car has a speed of 50 kilometers per hour. There is a clock which is 3 minutes per hour. If you use the clock to measure the speed of the car, what is the speed of the car?

Every hour is 3 minutes faster, so the hour of this watch is actually 60 / 63 hours, so
This is a measured velocity of 50 × 60 / 63 ≈ 47.619 (km / h)

Construction drawing budget and construction organization design of a class I Highway Section C
Abstract: as a part of Changzhou bid section of the extension project of Huning section of 312 national highway, the starting and ending mileage of the project is (k145 + 950 ~ K150 + 880), with a total length of 4.93 km
The budget statement of construction drawing of the project first introduces the function and compilation basis of construction drawing budget, In the highway engineering calculation, including the calculation of subgrade engineering quantity (subgrade cross-sectional area calculation and Subgrade Earthwork Calculation), pavement engineering quantity calculation, protection engineering and drainage engineering quantity calculation, and list the detailed bill of quantities; use Tongwang software to calculate the construction drawing budget of the project
In addition, the composition of highway engineering budget, related measurement rules and the use of Tongwang software are explained and introduced
The main contents of the construction organization design are: elaborated the preparation basis, scope, principle and project overview; determined the overall construction goal, analyzed the content of the general construction layout; elaborated the main content of construction preparation; specifically described the special subgrade treatment, subgrade filling, pavement structure and other construction schemes; and arranged the schedule of related projects
In addition, the quality, construction period, safety guarantee measures, civilized construction and environmental protection measures of the project are introduced in detail. The technical measures for special construction such as hot, rainy, winter and night are also introduced

From huangniutan east to Xiling, to Xiakou, the mountains and rivers are winding, and the mountains on both sides are heavily blocked, not in the middle of the day and the night, no sun and moon, cliffs or thousands of feet. Its stone color describes many kinds of things, trees are luxuriant, and winter and spring are slightly over. The apes sing to the clear, the valley sounds, and the water is cold
