Speed=distance / time
Data:
distance=240 m
time=6 s

Speed of this train=240 m / 6 s=40 m/s

The train pass through 480 meters of tunnel, therefore the distance will be:
distance of the tunnel + distance of the train= 480 m + 80 m=560 m

speed=distance / time   ⇒  Time=distance / speed
Data:

distance=560 m
speed=40 m/s

Time=560 m/ (40 m/s)=14 s

Answer: 14 seconds will take the train to pass through a 480 m long tunnel.

Answer:

Speed=distance / time

Data:

distance=240 m

time=6 s

Speed of this train=240 m / 6 s=40 m/s

The train pass through 480 meters of tunnel, therefore the distance will be:

distance of the tunnel + distance of the train= 480 m + 80 m=560 m

speed=distance / time   ⇒  Time=distance / speed

Data:

distance=560 m

speed=40 m/s

Time=560 m/ (40 m/s)=14 s

Answer: 14 seconds will take the train to pass through a 480 m long tunnel

Solve the following equation
Gnoma [55]
40x+8x^2=0 can be solved for x (there are two solutions):

Divide all 3 terms by the greatest common multiple (which is 8x):

40x+8x^2=0
------------- -----
       8x       8x

5 + x = 0             produces the root x = - 5.   

Setting 8x = 0 and solving for x produces the root x = 0.

Be certain to check these results.  substitute x = -5 into 40x+8x^2=0.  Is the resulting equation true or false?  Next, subs. x=-5 into 40x+8x^2=0.  Is the resulting equation true or false?
