Answer to Question #127025 in General Chemistry for Hannah Ruth

Question

A satellite is orbiting the earth at 1.75•10^5 mi/h. How many seconds does it take to travel 100 mi?

Answer 1

Speed of the satellite is 1.75*10⁵ mi/h

1 hr = 60*60 seconds = 3600 seconds

therefore 1.75&10⁵ mi are covered in 3600 seconds

100mi = ?

cross multiply

100mi * 3600 seconds/ 1.75*10⁵

^{which gives} 2.06 seconds
