Sandra needs to deliver 20 cases of celery to the farmer's market directly east across the river, which is 32 km wide. Her boat can move 2.5 km/h in still water. The river has a current of 1.2 km/h flowing downstream, which happens to be moving in a southerly direction. now she can take two routes, by boat or by walking and taking a boat. I cant figure out the amount of time its going to take for either route (boat and walk vs boat). I already completed most of the question, that's just the issue. I can provide my own work as an example
