a person travels equal distances with speeds of 6 km / hr , 12 km / hr , 18 km / hr . and takes a total time of 11 minutes . find the total distance ?
"let the each distance be x km total distance = 3 x then total time , ( x / 6 ) + ( x / 12 ) + ( x / 18 ) = 11 / 60 x = 0.6 total distance = 3 * 0.6 = 1.8 km = 1800 meters correct option is c"
multiply(multiply(divide(divide(11, const_60), add(add(divide(const_1, 6), divide(const_1, 12)), divide(const_1, 18))), const_3), const_1000)
