It takes 20 minutes for the oil to heat up to 300 degrees. It then takes 40% longer for the oil to heat up to the desired temperature of 400 degrees. After warming the oil it takes 5 minutes less time to cook than it took to warm up the oil. How much time passes from starting the oil to having cooked chicken?

How many minutes does it take to go from 300 to 400 degrees? ** It takes 20*.4=8 more minutes to go from 300 to 400 degrees than from room temperature to 300
How many minutes does it take to warm up the oil? ** So it takes 20+8=<<20+8=28>>28 minutes to warm up
How many minutes does it take to warm up the oil? ** So the total warming time was 28+20=<<28+20=48>>48 minutes
How many minutes does it take to cook the chicken? ** So it took 48-5=<<48-5=43>>43 minutes to cook the chicken
How many minutes does it take to make the chicken? ** So it took 48+43=<<48+43=91>>91 minutes to make the chicken.
