Fuzzy logic system used to determine the braking power car B that going behind car A$,$ depends on $2$ inputs distance between A and B and speed of B$,$ We need to build a fuzzy system of two inputs distance between A and B and Car B speed, one output which is the braking power, The distance range is between A and B $(0$ to $100)[$short medium long$]$ each fuzzy set range of medium is $[40$ to $80]$; the max value of short $50,$ the min value of long $70,$ Car speed in the range of $(0$ to $120)[$low Mid High$],$ The Mid$-$set range is $[40$ to $80],$ max low is $50$ Min high is $70,$ Braking power ranges $(0$ to $100)[$none Midd Hard$],$ Midd set $[35$ to $75]$; Max of none is $40,$ min of hard is $70.$ Rule: if the Distance medium and the speed is high then the braking is Midd, When the distance between A and B is $50$ and speed is $50,$ the braking power will be:Question $16$Answera.output equal $22\mathrm{.}5$b$.$output equal $54$c$.$None of the answersd.output equal $71$
