a train which has 600 m long , is running 60 kmph . in what time will it cross a person moving at 6 kmph in same direction ?
"time taken to cross a moving person = length of train / relative speed time taken = 600 / ( ( 60 - 6 ) ( 5 / 18 ) = 600 / 54 * ( 5 / 18 ) = 600 / 15 = 40 sec answer : d"
divide(600, subtract(divide(60, const_3_6), divide(divide(6, const_2), const_3_6)))
