Answer:

(a) 2.27 lb/$

(b) 0.10 mi/min

Explanation:

(a)

Pounds per dollar is found by dividing pounds by dollars:

(25 lb)/($11.00) ≈ 2.272727... lb/dollar

The digit in the thousandths place is less than 5, so that digit and all digits to its right are dropped when rounding to hundredths.

2.27 pounds per dollar

__

(b)

Speed in miles per minute is found by dividing miles by minutes:

(6 mi)/(58 min) ≈ 0.103448... mi/min

Rounding to hundredths is done the same way as above.

0.10 miles per minute

_____

If the digit to the right of the place you're rounding to is 5 or more, then 1 is added in the place you're rounding to when digits to its right are dropped.
