Answer - 37 minutes, also you should put that in math. explanation --> i did 20.00 - 13.34 which is 6.66 keep that number in mind since you are gonna have to multiply 0.18 a lot to get to 6.66, first i did 0.18 x 10 i got 1.80 since that wasn’t enough i did 0.18 x 20 next which is 3.6 since that also didn’t get to 6.66 i did 0.18 x 30 which is 5.4 i realized if i did 0.18 x 40 it would be over 6.66 so i did 0.18 x 35 which is 6.30 then 0.18 x 36 which is 6.48 then 0.18 x 37 which is 6.66 since i hit 6.66 were done we said 0.18 x 37 so you grab that 37 which is your answer “37 minutes”
