Am I working this problem correctly?
Two boats leave a dock at the same time. One boat is headed directly east at a constant speed of 35 knots(nautical miles per hour) and the other is headed directly south at a constand speed of 22 knots. Express the distance d between the boats as a funtion of the time t.
f(t)=sqrt(35^2 + 22^2)
Is that right?
