Equation:
b) How many miles is San Francisco from Tampa?
Answer:
Suppose that Ashley spent r hours driving from San Francisco to Tampa.
(1) Using Ashley's speed from San Francisco to Tampa, express the distance from San Francisco to Tampa through r.
(2) Use the distance from (1) and Ashley's speed from Tampa to San Francisco to express the driving time from Tampa to San Francisco through r.
(3) The driving time from San Francisco to Tampa, i.e., r, plus 10 hours plus the driving time from Tampa to San Francisco from (2) equals total trip time.
