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
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
Step-by-step explanation:
74939e+1364
Since y=x+1 plug it into bottom equation as y.
Subtract 1 from both sides
Subtract 5x from both sides
Divide both sides by -4
Now x=-3 into the top equation to find y
y=-2
the answer is 3 I bet the oven is hot tbh
