A train that is 80 meters long travels 240 meters in 6 seconds. How many seconds would it take the train to pass through a 480 m
eter long tunnel.
2 answers:
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

Answer:
B. 4/11
Solution:
Gradient=(y1-y2)/(x1-x2)
Gradient=(6-2)/(4-(-7)) =4/11
Answer:
x = 4
Step-by-step explanation:
subtract 2 from both sides. then -4x is equal to -16. divide by -4 which gives you 4. Hope this helped!
