Snail A 5 inches in 10 minutes Snail B 3 inches in 20 minutes Snail C 1 inch in 15 minutes Snail D 6 inches in 30 minutes
Which snail moves more quickly than the others? ____________ Explain how you figured this out.
Snail D moves more quickly than the others.
To figure this out, we can calculate the speed at which each snail moves. Speed is typically measured as distance over time.
For Snail A, the speed is calculated as 5 inches / 10 minutes = 0.5 inches per minute.
For Snail B, the speed is calculated as 3 inches / 20 minutes = 0.15 inches per minute.
For Snail C, the speed is calculated as 1 inch / 15 minutes = 0.067 inches per minute.
For Snail D, the speed is calculated as 6 inches / 30 minutes = 0.2 inches per minute.
Comparing the speeds, we can see that Snail D with a speed of 0.2 inches per minute is the fastest among the four snails.
how did you get the inches per minute
To calculate inches per minute, we divide the distance (in inches) by the time (in minutes).
For example, for Snail A, we divide the distance of 5 inches by the time of 10 minutes, resulting in a speed of 0.5 inches per minute (5 inches / 10 minutes = 0.5 inches per minute).
We follow the same process to calculate the speed for each snail, by dividing their respective distances by their times.
How far can snail D travel in 1 hour?
To determine how far Snail D can travel in 1 hour, we need to convert the time from minutes to hours.
Since Snail D moves 6 inches in 30 minutes, we can assume it moves at a constant speed. This means Snail D would also travel 6 inches in 60 minutes (since 60 minutes is equivalent to 1 hour).
So, Snail D can travel 6 inches in 1 hour.
. How far can snail C travel in half an hour?
To determine how far Snail C can travel in half an hour, we need to calculate its speed.
We know that Snail C moves 1 inch in 15 minutes. To convert this to half an hour (30 minutes), we can double the distance.
Therefore, Snail C can travel 1 inch in 15 minutes, so it can travel 2 inches in 30 minutes (or half an hour).
How far can snail B travel in 2 hours?
To determine how far Snail B can travel in 2 hours, we need to calculate its speed.
We know that Snail B moves 3 inches in 20 minutes. To convert this to 2 hours (120 minutes), we can multiply the distance by 6.
Therefore, Snail B can travel 3 inches in 20 minutes, so it can travel 18 inches in 120 minutes (or 2 hours).
