See explanation.

The distance on the plan is #2.5# inches. The real distance is: #90ft=90*12=1080# inches.

To calculate the scale we have to write the quotient of the 2 distances as a fraction with the numerator #1#:

#2.5/1080=5/2160=1/432#

Now we can write the answer:

The scale of Alvin's drawing is #1:432#.
