Answer: 528 km
Step-by-step explanation:
Let x be the total distance traveled by train.
Then, the total time he spent on looking outside the window and in sleeping = 
Then the remaining distance =
The time he spent on reading = 
Since, the train traveled 17.6 km more while he read than while he slept.
Then,
Hence, the train traveled 528 km.
Let's practice a little algebra and set the second distance to x.
9/4=270/x
solve
9x=270*4
x=30*4
x=120
The second distance is 120.
Done! any question about this just ask me in the comment.
Answer:
IQR = 5
Step-by-step explanation:
the IQR is the difference between the upper quartile Q₃ and the lower quartile Q₁
Q₃ is the value at the right side of the box plot , that is
Q₃ = 51
Q₁ is the value at the left side of the box plot , that is
Q₁ = 46
then
IQR = Q₃ - Q₁ = 51 - 46 = 5
14 divided by 20 is 0.7
Multiply that by 100
The answer is 70%
