Answer 1

Answer:

13

Step-by-step explanation:

Length of train = 256 m

Time to cross a tree = 8

Speed of the train = distance /time

Speed of the train = 32m/s

Length of bridge = 160m

Total distance = 256+160 = 416

Time taken to cross the bridge = 416/32

= 13 seconds

Answer 2

Answer:

Given,

Length of train, i.e. Distance = 256 m

Time = 8 second

Now, According to the formula,

Distance = Speed × Time

256 = Speed × 8

$Speed = \frac{256}{8}$

Speed = 32 m/sec

Now, we have to find total Distance,

Distance = 256 + 160 = 416

Time taken to cross a 160 m long Bridge = $\frac{416}{32}$

= 13 seconds
