Answer 2

Answer:

here's your answer, grab it

Step-by-step explanation:

GIVEN -

speed of the train - 40.5 km/hr

length of the train - 311m

( we know that whenever we have to solve these types of questions, we find out the distance adding the length of the train and station.)

so the distance will be -

$311 + 256 = 567$

formula -

speed = distance/time

now apply the formula -

(note : here , the values are in different units so we will also convert them to same unit during the calculation.)

${40.5 \times 1000} \div 60 \times 60= 567 \div time$

$time = 567 \div 11.25$

$time = 50.4 seconds$

Hence, the time taken to cross the platform will be 50.4 seconds
