8. Two trains are barreling down the track! Unfortunately, they are on the same track and headed for col- lision. The Orange Blossom Special left Sweet Town at 6 am traveling at a constant rate of 65 miles
per hour. The Early Bird left Wormville at 5 am traveling at a constant rate of 75 miles per hour. Sweet
Town and Wormville are 551 miles apart.
a. What is the exact time that the collision will occur?
b. From which town should they send the rescue vehicles? WI?

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

answer: 4

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.

110
