a student travels from his house to school at 10 km / hr and reaches school 1 hour late. the next day he travels 12 km / hr and reaches school 1 hour early. what is the distance between his house and the school?
multiply(multiply(10, 12), divide(subtract(12, 10), add(1, 1)))
let x be the distance from his house to the school . x / 10 = x / 12 + 2 6 x = 5 x + 120 x = 120 km the answer is e .
