A mile is longer than a kilometer. One mile is equal to 1.609 kilometers.
Answer:
Bridge = 300 m
Speed = 10 m/s
Step-by-step explanation:
If a goes past you in 10 seconds, it means the train has speed of
100 m/ 10 seconds as it is 100 m long
<u>The speed in m/s is:</u>
Then it take 3 times of 10 seconds to cross the bridge, so
<u>The length of the bridge is:</u>
Answer:
4
Step-by-step explanation:
The easiest way to solve this is just to put it in your calculator.
But if you want to go deeper, then ln(x)^4 = 4*ln(x)
Since x in this case = e then ln (e)^1 = 1.
ln(e)^4 = 4*ln(e) = 4
Answer: 22cm
Step-by-step explanation:
A square has four sides with equal length So, the perimeter of a square = 4L (i.e 4 x length)
= 4 x 5.5cm
= 22cm
Thus, the perimeter of the square is 22cm
