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

\[\frac{ 3,520ft }{ minute } \times \frac{ mile }{ 5,280ft } \times \frac{ 60minutes }{ hour }\]

Multiply across then divide. Be sure to cancel units as you come across them, for example: \[\frac{ feet \times inches \times cm }{ inches \times feet \times second }\]
Here since feet and inches are both on the top and bottom, we can cancel those out and be left with cm/second
\[\frac{ cm }{ second }\]

Answer 2

@Cupcake123456 "Which animal is faster and by how many miles per hour?"

They want it in miles per hour.

Answer 3

First we need to convert miles into ft. So, 30*5280=?15800 Now we need to convert the hour to minutes. That would be 158400/60. So, 2640 ft/min The White-Tail Deer's Speed= 2640 ft/min
The American Bison's Speed= 3520 ft/min

So, which one's faster?
