a person travels equal distances with speeds of 5 km / hr , 10 km / hr , 15 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 / 5 ) + ( x / 10 ) + ( x / 15 ) = 11 / 60 x = 0.5 total distance = 3 * 0.5 = 1.5 km = 1500 meters correct option is b"
multiply(multiply(divide(divide(11, const_60), add(add(divide(const_1, 5), divide(const_1, 10)), divide(const_1, 15))), const_3), const_1000)
