Problem not to scale!

I haven't been to work in a week-and-a-half and I have to say, this is great! I am taking the entire month of May off to study for the MCAT on May 31st - I meet my study partner J everyday at the UH library at 7:30am (give or take an hour - usually take :-) and we study all day. I am enjoying this so much - all the more proof that I really should spend my life in school!

Today I took a practice test to see how I was progressing. With about a minute left to finish the physical sciences portion of the test, I had one question left - and I was so confident in the answer that I didn't even bother doing any calculations. See for yourself (click on image to enlarge):


Considering that the HST was launched by the shuttle, and the shuttle's cargo bay is only about 20m long, I checked choice a) and confidently went to lunch. One problem - turns out the MCAT takes some 'poetic license' with real-life systems!

Lesson learned.

Actually, the focal length of the Hubble really is 58m (well, 57.6m), the primary mirror is 2.4m and the secondary is 0.3.

Obviously the real thing can't be 28m between mirrors, so the actual Hubble must have some additional feature.
