Question

From Direct and indirect variation so pls... use its formula​

Answer 1

Answer:

24 seconds

Step-by-step explanation:

Length of train = 440m = 0.44 km

Speed of train = 66 km/h

Since the point of reference is a person, it is considered as 0 length.

∴ Distance to be covered = length of train itself = 0.44 km.

$time = \frac{distance}{speed}$

$time = \frac{0.44}{66} \: \: hrs$

$time = 0.00666 \: ... \: \: hr$

∴ Time taken = 0.0067 hour (approx) = 24 seconds (approx)

Hope this helps you :)
