Yabbut, Mr Guthrie said to always show your work.


T/1 + T/2 = 1

1T + 2T = 2

3T = 2

T = 2/3 hour or 40 minutes

YMMV ... lol




Didn't Mr. Guthrie say anything about defining your variables?

IIRC, Mr. Guthrie said if you're smart enough to understand the problem
and show the work, he was certainly smart enough to deduce the variables
from the (con)text of the problem, and your answer.

Smart man, that Mr. Guthrie ... and hard to argue with.
