A car traveling at a certain constant speed takes 2 seconds longer to travel 1 kilometer than it would take to travel 1 kilometer at 300 kilometers per hour. At what speed, in kilometers per hour, is the car traveling?  Choose the correct choice from the following choices:
A) 300
B) 320
C) 330
D) 340
E) 290
300nswer 300   300 * T = 1 km =&gt; T = 1/360 km/h   V*(T+2/3600) = 1   V (1/360 + 2/3600) = 1 =&gt; V = 300 km/h
