tThe time taken by the slower train to pass the driver of the faster one is 24 sec.

Given that, two goods train each 500 m long, are running in opposite directions on parallel tracks. Their speeds are 45 km/hr and 30 km/hr respectively.

We need to find the time taken by the slower train to pass the driver of the faster one.

<h3>What is the relative speed?</h3>

The time after which both bodies meet = distance travelled / relative speed = dkm/ (x + y) km/hr. Now, we know that relative speed is the speed of one object with respect to another. So, if the time after which both the body moves is given, Suppose, time = t hrs.

Relative speed = (45 + 30) km/hr=75 km/hr

=(75× 5/18)m/sec

=(125/6) m/sec.

We have to find the time taken by the slower train to pass the driver of the faster train and not the complete train.

Here, distance covered = Length of the slower train.

So, the distance covered = 500 m.

Required time (500× 6/125​ )=24 sec

Therefore, the time taken by the slower train to pass the driver of the faster one is 24 sec.

The population of rabbits in a national forest is modeled by the formula P= 12,000 + 1000 (t+1) where t is the number of years f
V125BC [204]
In this formula, 1000(t+1) represents the growth rate of the rabbits.  We want the number right now, so sub in 0 for t.

P=12,000+1000(0+1)
P=12,000+1000
P=13,000 rabbits.
Hope this helps!!!

Please help<br><br> -3/4(8n + 12) = 3(n-3)
Dennis_Churaev [7]

Step-by-step explanation:

-  \frac{3}{4} (8n + 12) = 3(n - 3)

- 3(8n + 12) = 12(n - 3)

\cancel{- 3}(8n + 12) =  \cancel{12}(n - 3)

- (8n + 12) = 4(n - 3)

- 8n - 12 = 4n - 12

- 8n - 4n =  - 12 + 12

- 12n = 0

n = 0

Can someone help me &amp; show steps? Thank you
WARRIOR [948]

If this is a cube and each side is 6ft, each face will have an area of 6ft * 6ft, or 36ft. There are 6 faces on a cube, so 36ft * 6 = 216ft² as the surface area (it's also the same as 6³, fancy huh?)
