A penguin may swim as slowly as 3 miles per hour or as fast as 15 miles an hour. How many minutes does it take a penguin to swim 1 mile at full speed?
15/1 = 1/x
1/15 = 0.06667 hour = 4 minutes
To calculate the time it takes for a penguin to swim 1 mile at full speed, we first need to convert the speed from miles per hour to minutes per mile.
Since there are 60 minutes in an hour, we can divide the speed of 15 miles per hour by 60 to find the speed in miles per minute: 15 miles/hour / 60 minutes/hour = 0.25 miles/minute.
Therefore, it would take a penguin swimming at full speed approximately 4 minutes to swim 1 mile.
To calculate how many minutes it takes for a penguin to swim 1 mile at full speed, we can convert the penguin's speed from miles per hour to minutes per mile.
Since there are 60 minutes in an hour, we can divide the penguin's speed in miles per hour by 60 to get the speed in miles per minute.
15 miles per hour / 60 = 0.25 miles per minute
Therefore, it takes a penguin swimming at its maximum speed approximately 0.25 minutes (or 15 seconds) to swim 1 mile.
