Question

how long will a train 120 long take to clear a platform 130 metre long of its speed is 50 km per hour​

Answer 1

Answer:

first change speed in meter per second by multiplying by 5/18

speed = 50×5/18= 250/18 meter per second

Now use formula

time = distance ÷speed

time =250 ÷ (250/18)

= 18 seconds

THUS TIME TAKEN IS 18 SEC.

Step-by-step explanation:

distance = length of train + length of platform
