Each year wenford hospital records how long patients wait to be treated in the accident and emergency department.

in 2015 patients waited 11% less time than in 2014.
in 2015 the average time patients waited was 68 minutes.

the hospital has a target to reduce the average time patients wait to be treated in the accident and emergency department to 60 minutes in 2016.

work out the percentage decrease from 68 minutes to 60 minutes.

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)

inverse property is the answer
