A sloth moves as fast as it can 60 inches up a tree branch in 20 seconds. What is the sloth’s maximum speed as a unit rate in inches per second?(1 point)
To find the sloth's maximum speed as a unit rate in inches per second, we divide the distance (60 inches) by the time (20 seconds).
Maximum speed = Distance / Time = 60 inches / 20 seconds = 3 inches/second
Therefore, the sloth's maximum speed as a unit rate is 3 inches per second.
A plant manager counted 4,800 car parts that were produced on an eight-hour shift. What is the unit rate in parts per hour?(1 point)
Responses
0.002 parts per hour
6,000 parts per hour
600 parts per hour
60 parts per hour
To find the unit rate in parts per hour, we divide the number of car parts produced (4,800 parts) by the number of hours worked (8 hours).
Unit rate = Number of car parts / Number of hours = 4,800 parts / 8 hours = 600 parts per hour
Therefore, the unit rate in parts per hour is 600 parts per hour.
Mario walked 3,600 steps in 24 hours yesterday. How many steps did he walk per hour?(1 point)
To find the number of steps Mario walked per hour, we divide the total number of steps (3,600 steps) by the number of hours (24 hours).
Number of steps per hour = Total number of steps / Number of hours = 3,600 steps / 24 hours = 150 steps per hour
Therefore, Mario walked 150 steps per hour.
The newest John Deere combine machine can harvest 180 acres of wheat in 6 hours. How many acres will be harvested in 10 hours?(1 point)
To find the number of acres that will be harvested in 10 hours, we can set up a proportion based on the given information:
180 acres / 6 hours = x acres / 10 hours
To solve for x, we can cross multiply:
180 acres * 10 hours = 6 hours * x acres
1,800 acres = 6x
Divide both sides of the equation by 6:
1,800 acres / 6 = x acres
x = 300 acres
Therefore, in 10 hours, the John Deere combine machine will harvest 300 acres of wheat.
The finch population in an area increased by 75 finches in 3 years. How many finches did the population grow by each year?(1 point)
To find the number of finches the population grew by each year, we can divide the total increase in finches (75 finches) by the number of years (3 years).
Number of finches grown per year = Total increase in finches / Number of years = 75 finches / 3 years = 25 finches per year
Therefore, the finch population grew by 25 finches each year.
