Answer:
2 minutes
Step-by-step explanation:
The front of the train enters the tunnel and travels 1 km before the rear of the train enters the tunnel. Thus, the total distance traveled by the front of the train is 2 km, and this is covered in a certain number of hours:
Since distance = rate times time, time = distance / rate. In this particular case we have:
2 km
time = distance / rate = ------------------- = (1/30) hr
60 km/hr
(1/30) hr converts to 2 minutes, since 1 hr = 60 minutes
Hi!
Let's divide to solve this.
17.5 ÷ 8.75 = 2
The answer is 2 rooms.
Hope this helps! :)

52 + (-77) =
52 - 77 = -25
----------------------------
52 - (-77) =
52 + 77 = 129
---------------------------
your answer is: 52 - (-77)
To find the diameter of the radius you need to multiply 3.5 x 2 = 7
The slope-intercept form: y = mx + b
m - a slope
b - y-intercept (0; b)
-y + 8x = 2x |subtract 8x from both sides
-y = -6x |change signs
y = 6x
Answer: The slope m = 6, y-intercept b = 0 -> (0; 0).
