Let the width = x

length = 3x

Now, 2(3x+x) = 72

2(4x)=72

8x=72

x = 9

So, length would be 3x=3(9) = 27 meters

If a train traveled at 50 meters within 120 seconds, what is its speed?
Alja [10]

Answer:

v = 0.416 m/s

Step-by-step explanation:

Give that,

Distance covered by a train, d = 50 m

Time taken, t = 120 s

We need to find the speed of a train. The formula for speed of an object is equal to the total distance covered divided by total time taken. It can be given by :

v=\dfrac{d}{t}\\\\v=\dfrac{50\ m}{120\ s}\\\\v=0.416\ m/s

So, the speed of a train is 0.416 m/s.
