The plot below shows the amount of time Mira spent on 555 math problems. All measurements are rounded to the nearest \dfrac14 4 1 ​ start fraction, 1, divided by, 4, end fraction minute. If Mira had spent the same total amount of time, but spent an equal amount of time on each problem, how many minutes would each problem have taken? minutes

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4
