a white - tailed deer can sprint at speeds up to 30 miles per hour. american bison can run at speeds up to 3,520 feet per minute. which animal is faster and by how many miles per hour? there are 5,280 feet in one mile.
a deer is 10 miles per hour faster than a bison.
a bison is 10 miles per hour faster than a deer.
a deer is 0.66 miles per hour faster than a bison.
a bison is 0.66 miles per hour faster than a deer.

Explanation:

Step1: Convert bison's speed to miles/hour

First, convert feet per minute to feet per hour: $3520 \text{ ft/min} \times 60 \text{ min/hour} = 211200 \text{ ft/hour}$
Then convert feet per hour to miles per hour: $\frac{211200 \text{ ft/hour}}{5280 \text{ ft/mile}} = 40 \text{ miles/hour}$

Step2: Compare speeds and find difference

Deer speed: $30 \text{ miles/hour}$, Bison speed: $40 \text{ miles/hour}$
Difference: $40 - 30 = 10 \text{ miles/hour}$

Answer:

A bison is 10 miles per hour faster than a deer.
