the distance between a & b is 1540 km . a person is traveling from a to b at 100 km / hr started at 6 am and another person is traveling from b to a at 120 km / hr and started at same time . then at what time they meet together .
"let x hours be they will meet together distance covered by 1 st person + distance covered by 2 nd person = 1540 km 100 x + 120 x = 1540 x = 7 hr they will meet = 6 am + 7 hr = 1 pm answer is b"
divide(add(add(100, 120), 6), 120)
