Question

Jackrabbits are capable of reaching speeds up to 40 miles per hour. How fast is this in feet per second? (Round to the nearest whole number.)

5,280 feet = 1 mile

Answer 1

They already gave you the conversion, you can use fractions to set this up

You want to multiply this number by what was given above (5,280 feet = 1 mile)

Then convert hours to seconds using standard conversion measurements
[60 minutes in an hour --- 60 seconds in a minute]

\(\dfrac{211,200miles}{\color{red}{\cancel{1hr}}}\times \dfrac{\color{red}{\cancel{1hr}}}{60min}=\dfrac{\#mi}{1min}\)
[# is what you get from dividing 211,200 by 60]

\(\dfrac{\#mi}{1min}\times \dfrac{1min}{60 seconds}= mi/seconds\)
[Divide by 60 once again with the number you got from the first part. This should be your answer]
