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 450 kilometers per hour. At what speed, in kilometers per hour, is the car traveling?
Choose the most appropriate option
A) 370
B) 365
C) 360
D) 380
E) 350
360   450 * T = 1 km =&gt; T = 1/450 km/h   V*(T+2/3600) = 1   V (1/450 + 2/3600) = 1 =&gt; V = 360 km/h
