Question

The distance between two stations a and b is 280 km. One train at a speed of 80 kmph leaves station a at 6:00 pm towards station b. Another train at a speed of 120 kmph leaves station b at 7:00 pm towards station a. Then at what time both trains meet?

Answer 1

Let say  they meet T hr after 6 PM

Speed of 1st Train = 80 km/h

Distance by 1st train= 80*T km

Speed of 2nd Train = 120 km/h

Distance by 2nd Train = 120*(T-1)  ( as train leave (7-6=1hr) later

Distance covered by both train = 280 km

80T + 120(T-1) = 280

80T + 120T - 120 = 280

200T = 400

T = 2 Hr

6+2 = 8 PM

Train meets at 8 PM
