(i) the speed of the train, (ii) the time it will take to cross a bridge 450 m long.
Please answer fast.It's urgent

Answer 1

Answer:

(i) the speed of the train,

speed = Distance/Time

$= \frac{50 \: m}{5 \: s} = 10 \: \frac{m}{s}$

(ii) the time it will take to cross a bridge 450 m long

total distance = length of bridge + lenght of train

d = 450 + 50 = 500 m

$t = \frac{450 + 50}{10} = \frac{500}{10} = 50 \: seconds$
