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 Albert's unit rate in miles per hour, we need to divide the distance he walked by the time it took him.

The expression that can be used to calculate his unit rate in miles per hour is:

(4/5) / (5/12) miles per hour

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

(4/5) * (12/5) miles per hour

Which simplifies to:

48/25 miles per hour
