Question

Two trains 300 m and 450 m long are going in the same direction at 20 km/hr and 15 km/hr respectively. The shorter train is behind the longer train . How long would it take to pass each other?

Answer 1

Answer:

it take 9min to pass each other

Step-by-step explanation:

given

two train length 300m and 450m

velocity 20km/hr and 15km/hr same direction

calculation

shorter train behind the longer train so if pass each other then distance traveled by shorter train

= (300+450) = 750m velocity (20-15) km/hr = 5 km/hr

5km = 5000m travel in 1hr

1m travel in 1/5000 hr

750 travel in 750/5000 hr = 3/ 20 hr

= 3/20 × 60 minitue= 9minitue
