Question 323945: A train running at the speed of 60 km/hr crosses a pole in 9 seconds. What is the length of the train? solution: Speed= 60X5/18 m/sec = 50/3m/sec length of the train = S X D = 50/3 X 9m = 150m when do we use 5/18 ? Answer by mananth(16946) (Show Source):

A train passes two bridges of lengths 800 m and 400 m in 100 seconds and 60 seconds respectively The length of the train is?: Let s = the speed of the train in meter/sec Let L = length of the train: Write a distance equation for each bridge; dist = speed * time Train + bridge = total dist L + 800 = 100s L + 400 = 60s :

Question 1162031: A stone is thrown directly upward from a height of 30 ft, with an initial velocity of 60 ft/sec. The height of the stone, in feet, t seconds after it has been thrown, is given by the function: s(t) = -16t^2 + 60t + 30.
