A car traveling at a certain constant speed takes 10 seconds longer to travel 1 kilometer than it would take to travel 1 kilometer at 40 kilometers per hour. At what speed, in kilometers per hour, is the car traveling?	Choose the most appropriate option:
A) 35
B) 35.5
C) 36
D) 36.5
E) 37
40 * T = 1 km =&gt; T = 1/40 km/h   V*(T+10/3600) = 1   V (1/40 + 10/3600) = 1   V (100/3600) = 1   V = 36 km/h   The answer is 36.
