Ok, so Lexi has an 800 cm long roll of paper. And she needs to cut the paper into 1 meter strips. We know that 800 centimeters would need to be converted to meters in order to see how many 1 meter strips can be made from this roll of paper.
100 cm = 1 m
800 cm = 8 m
Since her roll is 8 m long, she should be able to make 8 strips to line the shelf in her pantry.
Answer:
75 feet per hour is the rate of change in altitude.
Step-by-step explanation:
A climber is on a hike. After 2 hours he is at an altitude of 400 feet.
After 6 hours, he is at an altitude of 400 feet.
We have to determine the average rate of change in altitude.
We know rate of change in altitude =
=
=
= 75 feet per hour
Therefore, 75 feet per hour is the rate of change in altitude.
