A sand

A sand timer has 5 5/16 ounces of sand. If the sand falls at a rate of 2.5 ounces per minute, how many minutes will the timer last? Write your answer as a fraction.

Correct answer:

t =  2 18 = 17/8 min

Step-by-step explanation:

a=5165=5+165=165 16+5=1680+5=1685=5.3125 oz v=2.5 oz/min  v=a/t  t=a/v=1685/v=5.3125/2.5=817 min=281 min=2.125 min
