Question

6. Two trains depart from a station in opposite directions at 120 km/h .Find the
distance between them after 20 min?​

Answer 1

Answer:

80km

Step-by-step explanation:

Distance = Velocity × time

Velocity= 120km/hr

time = 20 min = 20/60 hr = 1/3 hr

* Since both the trains are moving in the opposite direction,

total distance = distance travelled by 1st train + distance travelled by 2nd train

= X + X = 2x

Distance travelled by one train= 120 × (1/3)

= 40 km

Total distance = 2x = 2×40 = 80km
