To compare the speeds of the white-tailed deer and the American bison, we need to convert the bison's speed from feet per minute to miles per hour.
-
Convert bison's speed from feet per minute to miles per hour:
- The bison can run at 3,520 feet per minute.
- There are 5,280 feet in a mile and 60 minutes in an hour.
So, we first convert the speed to miles per minute: \[ \text{Speed in miles per minute} = \frac{3,520 \text{ feet}}{5,280 \text{ feet/mile}} = 0.66667 \text{ miles per minute} \]
Now we convert that to miles per hour by multiplying by 60 (since there are 60 minutes in an hour): \[ \text{Speed in miles per hour} = 0.66667 \text{ miles per minute} \times 60 \text{ minutes/hour} = 40 \text{ miles per hour} \]
-
Compare speeds:
- The white-tailed deer can sprint at 30 miles per hour.
- The American bison can run at 40 miles per hour.
-
Determine which animal is faster: The bison is faster than the deer.
-
Calculate the difference in speed: \[ \text{Difference} = 40 \text{ miles per hour (bison)} - 30 \text{ miles per hour (deer)} = 10 \text{ miles per hour} \]
Thus, the American bison is faster than the white-tailed deer by 10 miles per hour.
The correct statement from the given options is: A bison is 10 miles per hour faster than a deer.
