a person travels equal distances with speeds of 50 km / hr , 100 km / hr and 120 km / hr and takes a total time of 23 minutes . the total distance is ?
"let the total distance be 3 x km x / 50 + x / 100 + x / 120 = 23 / 60 23 x / 600 = 23 / 60 23 x = 230 x = 10 km total distance = 3 x = 30 km answer is b"
multiply(multiply(divide(divide(23, const_60), add(add(divide(const_1, 50), divide(const_1, 100)), divide(const_1, 120))), const_3), const_1000)
