Two surveyors with two-way radios leave the same point at 9:00 A.M., one walking due south at 3 mi/hr and the other due west at 4 mi/hr. How long can they communicate with one another if each radio has a maximum range of 4 miles?

Two girls with two-way radios are at the intersection of two country roads that meet at a $105^{\circ}$ angle (see the figure on the next page). One begins walking in a northerly direction along one road at a rate of $5 \mathrm{mi} / \mathrm{hr}$; at the same time the other walks east along the other road at the same rate. If each radio has a range of 10 miles, how long will the girls maintain contact? CAN'T COPY THE FIGURE
