Question 335599: Paul MacCready, the father of human powered aircraft invented the Gossamer Albatross, an aircraft which successfully flew the English Channel under human power (a cyclist turning the propeller). The aircraft flew from Folkestone, England to Cap Griz Nez, France, a distance of 22 miles, in approximately 3 hours fighting a headwind. On the return trip, this headwind would become a tailwind. Let us assume that the cyclist can pedal at a rate of 12 mi / hr without wind interference. Exhibit a rational expression for the round trip time, Folkestone to Cap Griz Nez and back, as a function of wind speed. What would be the domain of this rational expression?

Question 335791: How do you write this problem? Tow sailboats 400 meters apart are sailing toward each other. one is moving at a rate of 10m per sec and the other is moving at a rate of 15m per sec. in how many seconds will the boats pass each other? and in how may second will the boats be 400 meters apart again?
I think you write the problem like this
400=10m+15m
and
400=10m-15m
