When visiting his parents, tyler drives at an average speed of 42 km/h through urban areas and at an average speed of 105 km/h on the motorway. his journey usually takes him 2.5 hours. one day when there is fog, he sets off 1 hour early and only manages to drive at an average speed of 28 km/h in the urban areas and 60 km/h on the motorway. he arrives 30 minutes late. what was the total distance that tyler travelled?

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft

then say something, tell them they won’t respect you if you don’t even have respect for your self sweetheart you need to lay it on them, all of it : )

answer is (b.
