Andre rode his bike at a constant speed. He rode `2\frac{1}{3}` miles in `11\frac{2}{3}` min. Write an equation that represents the distance `d` he rides (in miles) after the time `t` (in minutes) he spent riding.

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
