If the time she rode her bike is 24, then 24*3 would be the Whole time she was there. She was there for a total of 72 hours.
Subtract 24 from 72 because it's 1/3 and you need the other time.
You get 48.
You need to find 1/4 of 48, so you divide it by 4.
48/4 = 12.
She rides the train for 12 hours. This is 1/2 of a day, so your answer is:
She rides the train for 1/2 of a day.

Cylinder is 10 meters wide, so its diameter is 10 meters. You get radius of it by dividing 10 by 2, which equals 5.
As you count volume of cylinder from that equation
You get an equation to count height:
h≈3.82 meters
Answer:
-14w²-7w+1
Step-by-step explanation:
(–7w2 – 2w – 1) – (–5w2 + 3w – 2)
-14w²-2w-2w-1 +10w²-3w+2
combine the like terms
-14w² + 10w² - 2w-2w-3w+2-1
-4w²-7w+1
