<human>:  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?
<bot>: 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.
