a person travels equal distances with speeds of 4 km / hr , 8 km / hr , 12 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 / 4 ) + ( x / 8 ) + ( x / 12 ) = 11 / 60 x = 0.4 total distance = 3 * 0.4 = 1.2 km = 1200 meters correct option is e
multiply(multiply(divide(divide(11, const_60), add(add(divide(const_1, 4), divide(const_1, 8)), divide(const_1, 12))), const_3), const_1000)
