In 1991, an American, Ann Trason, set a world record by running 1000 km in 7 hours, 50 minutes, and 9 seconds. Which is the best
Lyrx [107]
We know, speed = distance / time
Here, distance = 1000 Km
t = 7 5/6 = 47/6 hours

S = 1000 * 6 / 47
S = 6000 / 47
S = 127.65 Km/h

[ Please check your distance would be 100 Km i guess, if yes, then your answer will be B) 12 Km/hr ]

Hope this helps!

If a window is to be 6 feet wide, how high should it be, to the nearest tenth of a foot, to be a golden rectangle
slavikrds [6]

Answer:

3.7 feet

Step-by-step explanation:

A golden rectangle is a rectangle in which the length and the width are in the ratio 1 : 1.618

If the width of the rectangle is 6, the length = 6 / 1.618 = 3.708 ft

= 3.7 (to the nearest tenth)

the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
