The latest model of space shuttle can achieve a maximum speed of 25 miles per second. This maximum speed is how many miles per hour?

A. 1,500
B. 3,600
C. 9,000
D. 15,000
E. 90,000


Solution



Maximum Speed \(= 25\) miles per second

Maximum Speed in terms of hour \(= (25*60*60)\) miles per hour \(= (\frac{100}{4} * 60 * 60)\) miles per hour \(= \frac{36000}{4} = 9000\) miles per hour.

Correct Answer : Option C.

I think you forgot a zero. :?:

Shouldn't it be 360,000? Then \(\frac{360,000}{4}\)= 90,000.

C. 9,000
D. 15,000
E. 90,000

Since 1 hour = 3,600 seconds, the maximum speed is 25 x 3,600 = 90,000 mph.
