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 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"
divide(1, divide(add(multiply(const_3600, divide(1, 300)), 2), const_3600))
