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?
Answer/Solution
300
Steps/Work
Answer A
300 * T = 1 km => T = 1/360 km/h
V*(T+2/3600) = 1
V (1/360 + 2/3600) = 1 => V = 300 km/h
300 * T = 1 km => T = 1/360 km/h
V*(T+2/3600) = 1
V (1/360 + 2/3600) = 1 => V = 300 km/h
