Question

How long will a train, 120 m long, take to clear a platform, 130 m long, if its
speed is 50 km/hr?
Solve using direct and indirect variation.​

Answer 1

Step-by-step explanation:

Therefore total distance =

120+130= 250m= 0.25 km.

Speed of the train = 50km/hr

FORMULA=Time=distance/Speed

So time= 0.25/50hr= 1/200 hr

Now 1 hr = 3,600 seconds

Therefore, 1/200hr = 3600/200 = 18 sec

THUS THE TRAIN WULL TAKE 18 SEC TO CROSS THE PLATEFORM.
