Question

x and y are two stations 600 km apart. a train starts from x and moves towards y at the rate of 25 km/h. another train starts from y at the rate of 35 km/h. how far from x they will cross each other? * 1 point 250 km 300 km 450 km 475 km

Answer 1

Their rate of approach is 25 km/hr + 35 km/hr = 60 km/hr

600 km / 60 km/hr = 10 hr they will cross in 10 hrs

25 km/hr * 10 hr = 250 km

At 250 km from x they will cross
