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

Answer 1

To calculate his unit rate in miles per hour, we can use the expression:

(4/5 miles) / (5/12 hours)

This can be simplified by multiplying the numerator by the reciprocal of the denominator:

(4/5) * (12/5)

= 48 / 25

Therefore, Albert's unit rate in miles per hour is 48/25 mph.
