Question

Albert walks of a 4/5 mile in 5/12 of an hour. Which expression can be used to calculate his unit rate in miles per hour?

i multiply 5/12 by 4/5

correct?

Answer 1

Yes, that is correct. To calculate Albert's unit rate in miles per hour, you would multiply the distance of 4/5 mile by the reciprocal of the time of 5/12 hour:

(4/5 mile) / (5/12 hour)
(4/5 mile) * (12/5 hour) = 48/25 miles per hour

So, Albert's unit rate is 48/25 miles per hour.
