If Ben cycles from Town A to Town B at a speed of 10 km/h, he will arrive at 10 a.m. If he travels at 15 km/h, he will arrive at 8 a.m. At what speed must he cycle to arrive at 9 a.m.?
Write down the answer in km/h.
Gọi độ dài quãng đường từ A đến B là x(km)
(Điều kiện: x>0)
Thời gian Ben đi từ A đến B nếu đi với vận tốc 10km/h là: \(\frac{x}{10}\) (giờ)
Thời gian Ben đi từ A đến B nếu đi với vận tốc 15km/h là: \(\frac{x}{15}\) (giờ)
10h cách 8h là: 10h-8h=2h
=>\(\frac{x}{10}-\frac{x}{15}=2\)
=>\(\frac{3x}{30}-\frac{2x}{30}=2\)
=>\(\frac{x}{30}=2\)
=>x=60(nhận)
Khi Ben đi từ A đến B với vận tốc 15km/h thì thời điểm Ben xuất phát là:
\(8h-\frac{60}{15}h=4h\)
Thời gian từ 4h đến 9h là:
9-4=5(giờ)
Vận tốc Ben cần đi là 60:5=12(km/h)

Q9:THE PERIMETER OF THE SQUARE IS ;
8 X 4 = 32 ( CM )
SO , THE PERIMETER OF THE RECTANGLE IS 32 CM .
HALF OF THE RECTANGLE IS :
32 : 2 = 16 ( CM )
THE WIDTH OF THE RECTANGLE IS :
16 : ( 3 + 1 ) X 1 = 4 ( CM )
THE LENGTH OF THE RECTANGLE IS :
4 X 3 = 12 ( CM )
ITS AREA IS :
12 X 4 = 48 ( CM 2)
ANSWER : 48 CM 2
Q10: THE COST FOR 12 PEOPLE TO EACH OF A MOVIE KET IS :
5 X 12 = 60 ( DOLLARS )
THE COST OF A SOFT DRINK IS :
72 - 60 = 12 ( DOLLARS )
ANSWER: 12 DOLLARS

SKYTRAIN
Skytrain can replace many other systems because of its high-speed, low-cots, green, elevated, personal rapid transit.
Skytrain is a self-driving monorail designed to hover 20. feet above roads and travel up to 155 mph.The systems would turn a two-hour cả commute into a 10 minutes trip. The way it works would be through an app when you have to request a ride called 'a pod' putting your pick-up location and your destination in the Skytrain app like Uber. This means that unlike a typical subway system, Skytrain won't have a schedule, you will need to request your ride and get in when it shows up. Moreover, Skytrain is powered by clean, renewable energy. The minimal power that is needed to operate the skytrain maglev vehciles can be obtained almost entirely from clean energy such as solar power and emits virtually no pollution. Skytrain is expected to be used in United States by 2018.
1. Why the writer says that Skytrain can replace many other systems?
2. Which mean of transoprt is faster, the car or the skytrain? Why?
3. Does Skytrain need drivers?
4. How does Skytrain work?
5. Will Skytrain have a schedule? Why or why not?
6.What kinds of fuels can be used to operte Skytrain?
1.Because of its high-speed, low-cots, green, elevated, personal rapid transit
2.The skytrain is faster.Because the systems would turn a two-hour car commute into a 10 minutes trip
3.No,it doesn't
4.The way skytrain works would be through an app when you have to request a ride called 'a pod' putting your pick-up location and your destination in the skytrain app like Uber
5.Skytrain won't have a schedule.Because the way skytrain works would be through an app,you will need to request your ride and get in when it shows up
6.Clean energy such as solar power and emits virtually no pollution

giá năm tới: 260 + 260*5% = 273$
giá năm sau đó: 273- 273*5% = $259.35
giải thích: giá năm sau đó là $259.35 mà không phải $260 vì năm đó giảm 5% của $273

The route AB is 60km long. At 7 am, one motorbike travels from A to B with a constant speed. When this motorbike reaches B, it returns to A immediately with the speed increase by 10km/h and reaches A at 10.30 am at the same day. What is the original speed of this motorbike?
Note: You must write your answer in English.
Note: You must write your answer in English.
Exchange 2h30' = 2.5h
Let the real speed of the canoe be x (km/h) (x > 0)
=> Speed downstream: x + 8 (km/h)
Upstream speed: x-8 (km/h)
According to the arle we have (x+8).2 = (x-8).2.5 => 2x+16 = 2.5x - 20 => 0.5x = 36 => x = 72 (km/h)
=> distance from A to B = (72+8).2 = 160km
John drove from Town A to Town B in 5 hours. His average speed for the first 3.5 hours was 64 km/h. His average speed for the last 1.5 hours was 60km/h. What was the total distance he traveled?
duyệt đi
Quãng đường John lái xe được trong 3.5 giờ đầu là 64 x 3.5 = 224 (km)
Quãng đường John lái xe được trong 1.5 giờ cuối là 60 x 1.5 = 90 (km)
Tổng quãng đường John lái xe được trong suốt chuyến đi là 224 + 90 = 314 (km)
