The space shuttle travels at about 28,000 km per hour. Using that information, estimate how many hours it will take the shuttle to reach Saturn from Earth. Show your work. Convert your answer into scientific notation if necessary.

It depends on the location of the Earth and Saturn. Depending on whether the earth is between sun and saturn, or sun is between earth and saturn, the distance from earth to saturn varies. Obviously, if the earth is between the Sun and Saturn, the shortest distance will be. We will understand that the gap between Earth and Saturn is:    

Step-by-step explanation:

s = 1 275 000 000 km

The time required to travel that distance is:

t = s/v = 45535 hours or 1897.3 days

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
