distance (cự ly) time (thời gian) average speed (tốc độ trung bình) calculate (tính) equation (phương trình) |
The winner of the race is the person who hasthe fastest average speed.
To calculate average speed, you need the following equation:
distance/ time = average speed
distance: the race was 200m.
time: Fields completed the 200m in 161seconds.
So, average speed:
200/161 = 1.24 metres a second (m/s)
To calculate average speed in kilometres anhour (km/h), use this equation:average speed in m/s × 3.6 = average speedin km/h.
1 Look again at the table in exercise 1. Calculate the average speed of Gomez, Jones and O’Hara in m/s.
2 Now calculate the average speed of all the swimmers in km/h.
Tạm dịch:
Người chiến thắng trong cuộc đua là người có tốc độ trung bình nhanh nhất.
Để tính tốc độ trung bình, bạn cần công thức sau:
cự ly/thời gian = tốc độ trung bình
cự ly: cuộc đua là 200m.
Thời gian: Fields hoàn thành 200m trong 161 giây.
Vậy, tốc độ trung bình:
200/161 = 1.24 mét trên giây (m/s)
Để tính tốc độ trung bình tính bằng km một giờ (km / h), hãy sử dụng phương trình này: tốc độ trung bình tính bằng m / s × 3,6 = tốc độ trung bình tính bằng km / h.
1 Nhìn lại bảng ở bài tập 1. Tính tốc độ trung bình của Gomez, Jones và O’Hara theo m / s.
2 Bây giờ hãy tính tốc độ trung bình của tất cả những vận động viên bơi lội theo km / h.
1.
Gomez = 1.31 m/s
Jones = 1.25 m/s
O'Hara = 1.32 m/s
2.
Fields = 4.46 km/h
Gomez = 4.71 km/h
Jones = 4.5 km/h
O'Hara = 4.74 km/h

CAN I JUMP AS HIGH AS NBA* STARS?
No, you cannot if you do not eat as many calories as them. A basketball player needs between 2,500 and 5,000 calories per day. Bananas contain helpful nutrients that make the body feel full of energy. Each banana, on average, contains 30g of carbohydrates, and about 0.01g of vitamin C. Especially, bananas are a rich source of potassium, about 0.4g of each. Potassium reduces a sudden pain in muscles. That is why a wise basketball player often enjoys a banana before or during the game.
