We are given that the rate of a rocket is 41,400 kilometers per hour, or 41,400 km/1 hour, and we need to determine the speed in meters per second. Let's first convert kilometers to meters.AAPL wrote:Economist GMAT
A rocket is launched at 41,400 kilometers per hour. What the speed of the rocket in meters per second?
A. 115
B. 1150
C. 11,500
D. 69,000
E. 149,040
OA C
Since 1 kilometer = 1,000 meters, 41,400 km = 41,400 x 1,000 = 41,400,000 meters
We also know that 1 hour = 3,600 seconds.
So, our new rate is:
41,400,000 meters/3,600 seconds = 11,500 m/s
