Question

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.

Answer 1

Since the question is asking to compare both speeds in terms of mph it would be wise to convert the bison speed from feet/s to mph

First divide 3520 feet by the conversation 5280ft/mile, to convert to miles/second then multiply by the number of seconds in an hour (3600) to convert from miles/second to miles/hour

Then it's simply a matter of comparing which mph speed is greater and by how many mph
