A boat on the the ocean is 3 km from the nearest point on a straight shoreline; that point is 2 km from a restaurant on the shore. A woman plans to row the boat straight to a point on the shore and then walk along the shore to the restaurant. If she walks at 5 km/h and rows at 4 km/h. How far will the point on shore be from the restaurant if she plans to minimize her total travel time? Distance from restaurant = km
