17 km per sec
61,200 km per sec

17 km/s

Step-by-step explanation:

1.224 x 10^5 = 122400

There are 7200 seconds 2 hours

122400 / 7200 = 17

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
