Which detail from "Go, John Glenn!" best explains how long it takes Friendship 7 to completely circle the earth? "With each hour-and-a-half orbit of Earth, Glenn watched the sun rise and set." "Five hours and 81,000 miles after he had taken off, John Glenn splashed down to a welcome…." "For almost four hours he waited, on his back, his feet pushed up in front of him." "For twenty minutes, the capsule bucked and lunged while the temperature around it climbed."

Respuesta :

Answer:

"With each hour-and-a-half orbit of Earth, Glenn watched the sun rise and set."

Explanation:

According to the options above, we can see the time that Friendship7 takes to circle the earth is two hours. This is explained through the line "With each hour-and-a-half orbit of Earth, Glenn watched the sun rise and set," as it shows that every hour Friendship7 was able to circle half the earth, traversing the other half after one more hour and completing the orbit around the earth.  

Answer:

"With each hour-and-a-half orbit of Earth, Glenn watched the sun rise and set."

Explanation:

Friendship 7 made three orbits round the earth and this took a total of 4 hours 55 minutes. The orbital period in this case, is the time taken for Friendship 7 to complete an orbit round the earth. Since the total of three orbits took 4 hours 55 minutes, one orbit would take an hour and a half.

Therefore, the expression that would correctly how long it takes Friendship 7 to completely circle the earth, is the first sentence.
